|Electroless nickel-phosphorus-PTFE (Teflon) composite plating||- As the film composition, Teflon is contained by approximately 10 – 35vol% in a general nickel-phosphorus alloy matrix. The particle size of Teflon is approximately 0.2 - 0.3μm. The hardness is Hv400 – 700 (PTFE 12 – 28 vol%).
- Due to the low friction coefficient and self-lubricity (oil function) of Teflon particles, it is used on sliding surfaces for which lubricating oil cannot be used.
- While it has been found that nickel-phosphorus plating films exert antibacterial action, electroless nickel-Teflon composite plating combined with the non-adhesiveness (mold releasability) of Teflon particles is also used in the fields of manufacturing for foods, medicines, and nursing requiring washability and antibacterial properties.
