Physical vapor deposition (PVD) skills Physical vapor deposition (PVD) is the use of physical processes such as thermal transpiration, ion sputtering, or glow discharge; the ability to deposit the desired coating on the surface of the substrate. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
Physical vapor deposition can plate metal, alloy, oxide, nitride, carbide and other film layers, the film layer has strong adhesion; the process temperature is low; usually no or little deformation.
Including vacuum evaporation, ion sputtering, ion plating, etc.
1 ion sputtering coating skills:
Ion sputter coating technology is in the vacuum chamber; the use of energy-energy particles to bombard the surface of the target; through the momentum transfer of the particles to the atoms and other particles in the target; and its accumulation on the substrate to form a film.
Particle sputter coating can complete large-area rapid deposition; high coating density; good adhesion.
2 use:
Sputter coating data is not constrained; any material that can be made into a target can be sputtered into a film; widely used in mechanical, electronic, chemical, optical, plastic and other occupations.
Ion sputtering MoS2 is used for the bearing to deal with the smooth problem of the bearing; the solid self-smooth is completed.
The chemical vapor deposition technique is a chemical vapor phase growth method; it is a film that is rich in one or several compounds constituting a thin film element, a simple gas supply matrix; a chemical reaction that generates a demand by a gas phase effect or a chemical reaction on the surface of the substrate.
Coating layer: TiC, TiN, Ti (CN), Al2O3, ZrO2, TiO2 diamond or diamond-like.
Use CVD skills to complete the ceramization of steel balls or rollers; form a ceramic layer on the outer surface of metal balls or rollers; improve the wear resistance, temperature resistance, smoothness, corrosion resistance and other functions of the roll body. Bearing ball.
