Al2O3/SiC nano composite ceramics can replace wear-resistant and heat-resistant alloys used in preparing the arm-bush that is the key parts in the equipment of galvanizing steel strip. Conventional alloy for arm-bush could only operate 4 similar to7 days, and the ceramic Arm-bush can operate more than 100 days continuously tested in the same equipment and its service life has increased 15 times more than that of alloy. According to the results of microstructure analysis, one of the most important cause that the composite ceramics possess excellent wear-resistant properties in the fused zinc is that nano SiC particles have existed within fine grains of Al2O3.
