Abstract
The invention relates to a low-temperature normal-pressure plasma spraying process, which is characterized in that in the case of low temperature and normal pressure, a submerged arc is formed at the anode and the cathode of a high frequency power source, when the gas flows through the electrode, a new ionized form is generated and relatively cool plasma is formed, and then nickel-plated diamond particles, nickel-plated silicon carbide particles or cubic boron nitride particles are sprayed on the surface of a substrate by the plasma to form a coating having a thickness of 10-200mu m. A product prepared by the process disclosed by the invention has stable quality, the static friction coefficient of the fitting surface is greatly improved, the torque transmission efficiency of the power transmission system is improved and the service life is prolonged to some extent.
Description
Technical field
The invention belongs to plasma spray coating process field, be specifically related to a kind of low-temperature atmosphere-pressure plasma spray coating process.
Background technology
In motor car engine and dynamic transfer system component, as motor car engine crank axle, because work is turned round for a long time, vibrations are fierce, make fasten structural elements together also can produce fretting wear, thereby affect working efficiency, even cause potential safety hazard.
Summary of the invention
The object of the present invention is to provide a kind of low-temperature atmosphere-pressure plasma spray coating process, be applied in motor car engine and dynamic transfer system component, constant product quality, greatly improve the static friction coefficient of mating surface, the torque transfer efficiency that improves power drive system, improves work-ing life to a certain extent.
Technical scheme of the present invention is: a kind of low-temperature atmosphere-pressure plasma spray coating process; it is characterized in that: in low-temperature atmosphere-pressure situation; high frequency electric source forms buried arc at anode and negative electrode; when gas stream is through electrode; produce new shape ionized state and form relatively cooling plasma; spray nickel plating diamond particle, nickel plating silicon-carbide particles or cubic boron nitride to substrate surface with this, form coating.
Above-mentioned coat-thickness is 10～200 μ m.
Further, described coat-thickness is 50～80 μ m.
Beneficial effect: above-mentioned substrate surface is mainly the part that carries out tooth transmission; when the part of coating nickel plating diamond particle, nickel plating silicon-carbide particles or cubic boron nitride and mating parts are installed together; superhard particles can be embedded in mating surface inside, thereby greatly improves the static friction coefficient of mating surface.
Embodiment
Below in conjunction with embodiment, the present invention will be further described.
A kind of low-temperature atmosphere-pressure plasma spray coating process; in low-temperature atmosphere-pressure situation; high frequency electric source forms buried arc at anode and negative electrode; when gas stream is through electrode; produce new shape ionized state and form relatively cooling plasma, spraying nickel plating diamond particle, nickel plating silicon-carbide particles or cubic boron nitride to substrate surface with this.
Above-mentioned coat-thickness is 10～200 μ m.
Further, described coat-thickness is 50～80 μ m.
When the part of coating nickel plating diamond particle, nickel plating silicon-carbide particles or cubic boron nitride and mating parts are installed together; superhard particles can be embedded in mating surface inside; thereby greatly improve the static friction coefficient of mating surface, by experiment up till now can the maximum static friction that increases by 8 times.Thereby prevent from shaking fierce fastening piece and produce fretting wear, effectively prevent fastening structure becoming flexible in long-time use procedure.
