利用转盘式磨料磨损试验机考察了非晶态搪瓷涂层的磨料磨损性能，并分析了磨损机理.结果表明：搪瓷涂层磨损受磨料颗粒的种类及尺寸以及滑动速度的影响，其磨损机制主要为脆性剥落；这种脆性剥落源于滑动过程中涂层磨损表面的裂纹形成及其扩展.

The abrasive wear behavior and mechanism of an e namel coating were investigated with a rotary-disk-type abrasive wear machine. The worn surfaces of the enamel coating abraded with various sands were observe d with a scanning electron microscope (SEM). As the results, the abrasive wear o f enamel coating is governed by the sliding velocity and the type and size of th e abrasive particles. The abrasive wear of enamel coating is characterized by sp alling and microcrack, which are attributed to the formation of microcracks on t he worn coating surface and the propagation of the microcracks.
