Description
Technical Field
The application relates to the technical field of metal surface coatings, in particular to an aviation broach surface coating and a preparation process thereof.
Background
The broach is a multi-tooth precise precious tool, and is mainly used for mass production and high-precision machining of metals. The broach has various movement modes during working, such as linear movement or circular movement, workpiece movement or broach movement, or the broach and the workpiece move simultaneously, and the complicated processing state brings great requirements on the material properties of the broach, such as strength, toughness and the like.
For the material of the broach, common high-speed steel, high-performance high-speed steel, hard alloy and the like can be selected. Because of the difficult grinding processing of the hard alloy material, the prior art is rarely adopted, and the prior broach mostly adopts high-performance high-speed steel. Factors restricting the development of the high-speed steel tool mainly include hardness, toughness, wear resistance and red hardness. In order to improve the cutting performance of the high-speed steel cutter, the technician needs to carry out coating treatment on the surface of the cutter so as to enable the cutter to have better processing performance.
The existing coating treatment process of the broach comprises boronizing and metal-infiltrating, and the coating formed by the boronizing treatment process is thicker, but the coating has high brittleness and poor oxidation resistance and corrosion resistance; the coating formed by the titanizing treatment process has higher microhardness, but the treatment temperature is high, the coating is generally thinner, and a carbon-deficient area exists in the coating, so that the workpiece is deformed greatly and the bearing capacity is poor. In other coating treatment processes, the problems of uneven distribution of elements in the formed coating, easy occurrence of cracks and the like caused by poor dispersity of permeable materials exist.
Disclosure of Invention

the pretreatment of the coating raw materials is specifically as follows: uniformly mixing the raw materials except aluminum powder according to a certain proportion, grinding, adding ethyl silicate accounting for 8% of the total weight of the coating raw materials, 3.5% of a gel dispersing agent and 2% of a KH570 coupling agent, mixing into paste, and roasting for 2-3 hours at the temperature of 350 ℃; finally cooling, crushing, adding aluminum powder, and grinding to finish pretreatment;

1) 100g of cyclodextrin, 200g of carbomer, 500g of deionized water and 15g of quaternary ammonium base are put into a reaction kettle and uniformly mixed to prepare a precursor liquid;
2) Slowly adding 50g of salicylaldehyde and 200g of absolute ethyl alcohol into the precursor liquid, heating to 70 ℃ for reaction for 3 hours, adding 20g of paraaminobenzoyl chloride, and continuing to react for 1.5 hours to obtain the catalyst;
s2: pretreating the surface of an aviation broach, placing the pretreated aviation broach into a coating raw material, tabletting by a tablet press, burying the aviation broach into a corundum crucible, and placing the crucible into a muffle furnace;
s3: heating to 950 ℃, maintaining the temperature, and performing coating permeation operation for 4-5 h.
Preferably, in the step 1), the quaternary ammonium base is one of tetraethylammonium hydroxide, tetrapropylammonium hydroxide and tetrabutylammonium hydroxide.
Further preferably, in the step 1), the quaternary ammonium base is composed of tetraethylammonium hydroxide and tetrabutylammonium hydroxide according to a mass ratio of 1:2.5.
Preferably, in the step S3, the temperature is raised to 950 ℃ according to a temperature raising control curve, and the fitting equation of the temperature raising control curve is y=25+33.5x-0.285X 2 Wherein Y represents temperature, and the interval of Y is [25, 950] and the unit is DEG C; x represents time in min.
Further preferably, the correlation coefficient of the fitting equation is 0.95.
Preferably, the rare earth oxide is CeO 2 、La 2 O 3 Or Nd 2 O 3 。
Preferably, in the step S2, the preprocessing the surface of the aviation broach includes: removing oil stains on the surface, cleaning with deionized water, polishing the surface with sand paper, cleaning with acetone and ultrasonically cleaning with deionized water.
Further preferably, in the step S2, the surface roughness Ra after sanding the surface is less than 0.05 μm.
Further preferably, the mesh number of the sand paper is 400#, 600#, 800#, 1000#, 1500#, 2000#, in sequence.
In a second aspect, the present application provides an aviation broach surface coating, made by the above-described manufacturing process.
The application has the following beneficial effects:
1. the co-boronized titanium element is adopted, so that the surface hardness, wear resistance, heat resistance, cutting performance and hot corrosion resistance of the high-speed steel can be effectively improved, and the high-speed steel is suitable for application under high-temperature, high-speed and heavy-load working conditions. In addition, the surface coating generally has good bond strength and a low coefficient of friction, enabling it to increase the working life and the use of high speed steel.
2. Boron nitride has extremely high hardness and wear resistance, zirconium oxide has high temperature stability, titanium aluminum carbide and titanium carbide provide high hardness and excellent cutting performance, rare earth oxide can improve hot corrosion resistance, and interaction between the additives can comprehensively exert respective advantages, so that the coating has more excellent comprehensive performance. The titanium aluminum carbide can be used as a diffusion aid of the coating to enhance the forming rate and the diffusion depth of the coating. Boron nitride, zirconia, titanium aluminum carbide, titanium carbide and rare earth oxide mutually promote in the infiltration process, cooperatively exert respective advantages, react or interact with each other at high temperature to form a stable coating with excellent properties, and can remarkably improve the properties of hardness, wear resistance, heat resistance, hot corrosion resistance, cutting performance and the like of high-speed steel.
3. According to the preparation method, the raw materials are ground and then are mixed into paste through ethyl silicate and KH570 coupling agent, and the paste is baked and re-ground, wherein the ethyl silicate is a surfactant, and in the raw material mixing process, particle aggregation and accumulation can be reduced through reducing the surface tension and friction between the powder, and the fluidity and dispersibility of the powder are promoted, so that the mixing uniformity of each component is improved; the KH570 coupling agent can form coupling combination on the surface of powder particles, reduce the surface energy of the powder particles, reduce the aggregation phenomenon of the particles, and promote the dispersibility of the particles at the same time, thereby promoting the mixing uniformity of raw materials. And after the gel dispersing agent is added, an adsorption layer can be formed on the surface of the particles, so that the slip among the particles is increased, and the agglomeration caused by the micro-nano effect of the particles is reduced. In addition, salicylaldehyde in the gel reacts with free amino groups and hydroxyl groups in carbomer and cyclodextrin molecules to generate Schiff base derivatives, then reacts with para-aminobenzoyl chloride, polar groups such as amino groups are introduced into the system, and meanwhile, the activity of hydroxyl groups in the system is activated, so that the surface energy of raw material particles can be adjusted, the degree of freedom of each component is improved, the compatibility and dispersion among raw material particles of each component are promoted, and the uniform permeation effect is further improved. The use of ethyl silicate, gel dispersant and KH570 coupling agent can make powder particles more uniformly dispersed in the matrix, and the powder particles fully contact and react, so as to reduce the degree of particle agglomeration, thereby improving the mixing uniformity of the powder raw materials and finally improving the uniformity of the coating.
