摘要
Two new coatings based on graphite and MoS2 have been developed. They combine low friction with high hardness, high load capacity and exceptionally low wear. Both coatings act as solid lubricants, providing protection for both the coated surface and any opposing uncoated surface. The coatings are finding application in improving the general performance of cutting and forming tools and also make possible high-speed machining. The graphite-based coatings have exceptional wear properties under water or oil and results from wear tests under a wide range of conditions are given. A number of practical applications are given, including the protection of artificial hip joints. The advantages offered by the use of such coatings for many mechanical components are demonstrated.
