Abstract
Based on surface protection problems of the steel part of the landing gear, wear-resisting properties of tungsten carbide-cobalt (WC-Co) particles reinforced epoxy (WRE) coatings were investigated in this paper. The curing process of WRE coating was analyzed by DSC, TG and IR. The wear performance under different rotational speed WRE coating was studied respectively. The specific wear rates of the WRE coating at 560 rpm and 840 rpm are 6.04 ×10−4 mm3N−1 m−1and 9.55 ×10−4 mm3N−1 m−1 respectively, about only 60% of that of the uncoated sample. Thus, this could be summarized that WRE coating had a good wear resistance.
