159 results about "Surface finishing" patented technology

Surface finishing is a broad range of industrial processes that alter the surface of a manufactured item to achieve a certain property. Finishing processes may be employed to: improve appearance, adhesion or wettability, solderability, corrosion resistance, tarnish resistance, chemical resistance, wear resistance, hardness, modify electrical conductivity, remove burrs and other surface flaws, and control the surface friction. In limited cases some of these techniques can be used to restore original dimensions to salvage or repair an item. An unfinished surface is often called mill finish.

To provide improved surgical instruments. [Solution] Surface preparation of sliding surfaces can improve the wear performance of surgical instruments such as surgical staplers, which include a reusable mechanism that is used multiple times with a single-use reloadable cartridge. A combination of surface hardening, surface finishing, and surface coating can be applied to the metal components of surgical instruments to reduce the possibility of abrasive wear in metal-to-metal sliding engagements. Surface hardening technology can enable further manufacturing operations such as welding without compromising the strength of the underlying metal substrate. With stainless steel metal substrates, surface hardening or surface hardening technology may reduce corrosion resistance, so a surface coating can be added to suppress surface oxidation and to provide a barrier against metal-to-metal contact. Further lubricating coating layers, such as a brazing coating layer, can enhance abrasion resistance.
