英文摘要：

The latest progress in surface modification of steel substrates with diamond coatings was tentatively reviewed. The diamond coatings on steel substrate have found increasingly wider applications because of its favorable mechanical properties, such as its extremely high hardness and wear resistance, low friction coefficient, and good thermal con- ductivity. The discussions centered on： i）two major problems in synthesis of diamond coatings by chemical vapor deposition（CVD）, one is the catalytic effect of Fe, Ni, Co, and alloys on formation of graphitic carbon materials and the other is the poor interfacial adhesion because of release of stress and strain at the interface in the cooling induced phase transition from austenite to pearlite or austenite to martensite; ii）possible solutions including growth of a variety of composite transition multi-layers capable of blocking inter-diffusion of Fe, Ni, Co, C, and improving the interfacial adhesion; and iii） advanced technologies in synthesis diamond coatings on austenitic stainless steel and high alloy steel. The development trends in deposition of diamond coating on steel were also briefly discussed in a thought provoking way.
