Surface treatment technology over the past decade to form and the rapid development of a discipline, why should the bearing surface to bearing more suitable for high-temperature, high-pressure, high-speed, heavy-duty, as well as corrosion and so on a variety of environmental, Today we'll talk about several of the bearing surface treatment technology
1, the ion implantation processing techniques on the surface: the ion-implanted surface is some atoms of elements in ionized into a plasma and to accelerate it in the machine ten to several hundred kilovolts, the incident side in a higher speed An ion beam processing of the surface of the workpiece in the target chamber of vacuum technology.
Ion implantation technology Features: A significant improvement in wear resistance, corrosion resistance, high temperature resistance and light, electricity, superconductivity and other properties of the material; traditional surface alloy layer from equilibrium, solid solution alloying rules limit , in principle, any element (s) can be injected into any matrix metal; C, between the ion implantation layer and the base material is no interface, there is no combination of bad flaking;, no environmental pollution
Ion implantation techniques Applications: A, for tools, cutting tools, molds and other ion implantation, dramatically increase the life of the rolling body tooling B, for large bearing roller and the surface treatment of the steel ball, to obtain the desired high temperature, corrosion electromagnetic, self-lubricating characteristics, especially for large-size parts matrix may be relatively low price of materials, ion implantation is performed, to obtain the desired surface alloyed layer, to achieve the combination of high energy ion beam or a laser surface treatment technology required performance, parts manufacturing solve the overall material universal heat treatment or processing methods can not achieve.
2, the laser beam surface modification technology: laser beam surface modification technology is applied to the material surface high energy, so that the occurrence of physical and chemical changes can significantly increase the hardness of the material, strength, wear resistance, corrosion resistance and high temperature performance, etc., thus greatly improving product quality, extend product life and reduce costs exponentially, achieved tremendous economic benefits.
Laser beam surface modification technology advantages: A heat treatment depth is small and easy to control; B, the energy density of the laser spot can be accurately guided to the ground in different parts of the surface; C, after processing small deformation; D, easy to transport, switch and automatic control. E, chemical pollution, and help protect the environment. Laser surface modification transformation hardening, fused coating, alloying, amorphization and MICROCRYSTALLIZATION to, the impact of enhancement.
The laser beam surface modification technology applications: for rolling body surface modification, such as carbon steel ball after crossing chromium, surface-modified with a laser beam, the performance of the stainless steel balls can be obtained.
3, a physical vapor deposition (PVD) technologies: physical vapor deposition (PVD) technology is the use of thermal evaporation, ion sputtering or glow discharge, and other physical processes, the desired coating is deposited on the substrate surface technology. Physical vapor deposition coating the coating of metals, alloys, oxides, nitrides, carbides, etc.; film adhering ability, the process temperature is low, usually no or little deformation. Including vacuum deposition, ion sputtering, ion plating, etc..
4, the ion sputtering technique: ion sputtering technique in a vacuum chamber, the use of energetic particles bombarding the target surface, pass through the momentum of the particles hit the target atom, and other particles, and so that it is deposited on the substrate forming a thin film technology. Particle sputtering coating to achieve a large area of rapid deposition, high density coating adhesion.
Ion sputtering technology applications: sputtering coating material is unrestricted, where the material can be made the target sputtering film formation can be widely used in machinery, electronics, chemical, optical, plastic and other industries. Ion sputtering MoS2 solve for bearing bearing lubrication, solid self-lubricating. The can coating layer: TiC, TiN, Ti (CN), Al2O3, ZrO2, TiO2 diamond or diamond-like carbon. CVD technique can be realized a ball or roller ceramming in the metal ball or roller surface of the ceramic layer is formed to improve the bearing rolling elements, abrasion resistance, temperature resistance, lubricity, corrosion resistance and other properties. Such as aircraft doors bearing ball.
