Abstract
A novel method was introduced in this article to fabricate hybrid materials by virtue of thermal sprayed ceramic coatings as templets to improve their tribology performance. MoS2 was in-situ synthesized in the pores and micro-cracks of ceramic coatings using hydrothermal method coupled with vacuum impregnation. The resultant MoS2 appeared flowerlike microsphere structure and constructed with many ultrathin nanosheets, which were curly and interconnected to grow in the pores and micro-cracks of ZrO2 coatings. The results of tribological test revealed that the composite coatings have excellent tribological properties due to the formation of MoS2 lubricating film on frictional surfaces in comparison with pure ZrO2 coatings.
