A new technique to enhance film-coating processes in oil-based medial

摘要

A new technique was developed to deposit phosphate films on irregular shaped iron or steel components. This technique is a chemical process, and it does not need any external power supply. The phosphate films thus coated are beneficial in reducing both friction and wear. Co-deposition of copper and zinc along with the phosphate is also demonstrated. This process could lead to the tailoring of the friction and wear properties of coatings by introducing various metals. In addition, the co-depositionof copper and zinc demonstrates that the lubricant can serve as a medium for the transport of ionic species.
