Abstract
The present utility model discloses a ceramic coating piston rod with thermal spraying. It is characterized by that said piston rod includes a piston rod matrix, on said piston rod matrix a ceramic coating is covered. Said ceramic coating is with the beneficial effects of excellent wear resistance, low friction coefficient of coating and low friction power loss during the running of piston rod. Said ceramic coating has the advantages of high stability, good water-resistant and moisture-resistant. The present utility model is with advantage of easy manufacturing, it can reduce easily the environmental pollution caused by free Cr-plating, and can be applied to the travel-control signal sensor, and have the advantages of precise measurement, flexible control, safety and stabilization.
Description
Technical field;
The utility model relates to large hydraulic equipment, is a piston rod part that is used for the large hydraulic hoist, specifically, is a kind of Thermal spraying ceramic coat piston rod.
Background technique:
The large hydraulic hoist is used in the keying of the gate of Large Hydro-Junction engineering usually, be the key equipment of water conservancy dam, its performance and working life are for the normal operation of anti-baking, flood discharge, shipping and the water generating equipment of dam and guarantee that the safety of dam all has crucial meaning.And the piston rod of the hydraulic jack of hydraulic hoist not only will bear the wearing and tearing in reciprocatingly sliding under the heavy duty when opening and closing gate, also must be in the face of the corrosion of open-air humidity, steam, water temperature, waterline variation etc.Traditional chrome-plated piston bar decay resistance is good inadequately, oil leakage phenomenon often occurs after use a period of time, even " stuck ", directly has influence on the keying and the location of gate.Therefore, traditional chrome-plated piston bar can not satisfy high-performance, long lifetime, few requirement of keeping in repair of hydraulic engineering to its proposition.
Summary of the invention:
The purpose of this utility model provides a kind of wear-resisting property excellence, and the friction factor of coating is low, can reduce the operating frictional work loss of piston rod.Ceramic coating has high stability, and water-fast vapour corrosivity is fabulous.Environmental pollution easy to process, that cause on the easy hard road of grinding electroless plating.Also can be used for the Stroke Control signal emitter, measure accurately, control Thermal spraying ceramic coat piston rod flexible, safety and stability.
Technical solution of the present utility model is: a kind of thermal Sperayed Ceramic Coatings cold bar alive is characterized in that: the piston rod matrix is arranged, be coated with ceramic coating on the piston rod matrix.
Be processed with screw channel at the piston rod matrix surface described in the utility model, the ceramic coating of spraying is positioned at screw channel.Spray surface that has behind the ceramic coating and the piston rod surface of not opening screw channel in the screw channel and constituted smooth surface.
The beneficial effects of the utility model are: the coating hardness height, and the wear-resisting property excellence, coating hardness HV can reach 950-1400.The friction factor of coating is low, and is little to the friction factor of filler idol part, and can reduce the operating frictional work loss of piston rod.Ceramic coating has high stability, and water-fast vapour corrosivity is fabulous.Easy to process, easy grinding also is ground to high degree of finish, and surface roughness can be controlled between the Ra0.55-0.99 11 μ m.The environmental pollution that the electroless plating hard chrome causes, the issuable worry of oozing hydrogen, hydrogen embrittlement of electroless plating chromium.Seawater corrosion resistance, and do not adhere to the living marine growth that adheres in sea, this is very favourable with the normal operation of hydraulic cylinder piston rod for ocean environment.Also can be used for the Stroke Control signal emitter, measure accurately, control flexible, safety and stability.Carry out the displacement sensor control and accurately measurement automatically of piston rod stroke easily.
Below in conjunction with drawings and Examples the utility model is further described:
Description of drawings.
Accompanying drawing is the structural representation of a kind of Thermal spraying ceramic coat piston rod of the present utility model.
Embodiment;
Accompanying drawing has been described an embodiment of the present utility model, in this embodiment, piston rod matrix 1 is arranged, and is coated with ceramic coating 2 on piston rod matrix 1.Described have screw channel in piston rod matrix 1 surface Machining, and the ceramic coating 2 of spraying is positioned at screw channel.Spray surface that has behind the ceramic coating 2 and the piston rod surface of not opening screw channel in the screw channel and constituted smooth surface.Smooth surface utilizes refining surfaces and forms.In use, utilize Standpoint of Ceramic Wear-resisting Function energy and insulating property, the formed ring crown of the unslotted part of piston rod matrix then has metal magnetic, can be used as sensor.
Claims (2)
1, a kind of Thermal spraying ceramic coat piston rod is characterized in that: the piston rod matrix is arranged, be coated with ceramic coating on the piston rod matrix.
2, Thermal spraying ceramic coat piston rod according to claim 1 is characterized in that: be processed with screw channel at the piston rod matrix surface, the ceramic coating of spraying is positioned at screw channel.
