Technical Field
The invention belongs to the field of metal materials, and relates to a manufacturing method of a low-friction-coefficient corrosion-resistant blade material of an ice skates.
Background
Speed skating is a racing sport performed on ice by taking a skates as tools, and the sport efficiency of athletes is related to the technical actions of the athletes, and the performance of the skates has an important influence on the performance of the athletes. The performance of the blade as the part of the blade contacting the ice surface directly determines the usability of the blade. The ideal blade material should have high wear resistance, low friction coefficient with ice surface and high toughness, and simultaneously have good corrosion resistance. The blade for athletic is made of bimetal material and consists of a back material and a blade, wherein the back material has high elasticity, and the blade has high wear resistance. In spite of excellent mechanical properties and wear resistance, the corrosion resistance of the existing blade is slightly insufficient, and the blade is easy to rust when not used for a long time. In addition, the existing blade is formed by welding two materials, the working procedure is complex, a single-material blade is developed, and meanwhile, good mechanical property, wear resistance and corrosion resistance are all trends of future development.
Disclosure of Invention

A manufacturing method of a low friction coefficient corrosion-resistant blade material of an ice skates is characterized by comprising the following steps:
1) The preparation mass ratio is C:1.8 to 2.1 percent, cr:13.5 to 14.5 percent, V:12 to 12.5 percent, mo:1.5 to 1.8 percent of spherical metal powder of which the balance is Fe and the granularity is less than 200 mu m;
2) Filling the powder into a stainless steel sheath, vacuumizing, and performing hot isostatic pressing sintering;
3) Removing the sheath from the sintered hot isostatic pressing ingot, and forging and rolling the hot isostatic pressing ingot into a narrow band;
4) Quenching the narrow band to obtain the high-performance blade material of the skates.
Further, the sintering temperature in the step 2) is 1180-1200 ℃, the sintering pressure is 120-130 MPa, and the sintering time is 90-120 minutes.
Further, in the step 3), the starting temperature of forging and hot rolling is 1150+/-10 ℃, the ending temperature is 950+/-10 ℃, and the thickness of the plate blank after hot rolling is 1.20-1.21 mm.
Further, the quenching temperature in the step 4) is 1180-1200 ℃, and the air cooling is performed after heat preservation for 8-10 minutes.
The invention is characterized in that a single material is used as the blade material, and the defect that the prior blade is formed by welding two materials and has complex working procedures is overcome. The VC phase in the material accounts for 13-15% by mass, and meanwhile, the heat treatment process is only quenching treatment and tempering is not needed. The blade is guaranteed to have low friction coefficient, and meanwhile, the blade also has high mechanical property and corrosion resistance.
The main mechanism of the design alloy composition of the invention is that a proper amount of four alloy elements of C, cr, mo and V are added into Fe, and a high-hardness matrix and a VC combined structure are obtained through quenching treatment, and the matrix has high hardness, strength and corrosion resistance due to the fact that a large amount of C, cr, mo and V elements are dissolved in the matrix, meanwhile, the alloy composition has a low friction coefficient with ice surface, the mass percentage of VC phase is 13-15%, the blade is ensured to have good wear resistance, and meanwhile, the friction coefficient with ice surface is not influenced due to the excessively high content. It is to be noted that the heat treatment process adopted by the invention only has quenching and no tempering, because the tempering can cause a large amount of carbide to be separated out from the matrix to affect the hardness of the matrix, and meanwhile, the separated carbide is granular, the friction coefficient of the blade and the ice surface can be increased, so that the quenching treatment is only carried out on the basis of component design, the blade is ensured to have low friction coefficient, and meanwhile, the blade also has high mechanical property and corrosion resistance.
