For other coating layers, separation happened after 2,000 shots. However, separation of F coating can hardly be found after 10,000 shots. This indicates enhanced adherence has improved wearability, and special surface treatment has superior shock resistance. Compared with TD treatment of high rigidity, the adherence and shock resistance of F coating are greatly improved. And compared with WPC＋TICN, the base material hardness and the special treated surface thickness of F coating r are also improved.Aspect ②Aspect ①Aspect ③Pictures are taken from 3 different aspects of the retainer.Drawing 5／F coatingDrawing 8／Camera aspectsDrawing 6／TD processDrawing 7／WPC＋TiCN1109Testing result & consideration
