ÎÒÒ²²»¶® ½ö¹©²Î¿¼ 1) the two coating are covered with a dense microstructure and show comprised of ¦Ã-Al2O3 with some amorphous; 2) Both two coating are covered with a good anti-skidding property; 3) Tribology tests show that the two coatings have excellent wear resistant. The wear is " pulled out" at lower speed leading to the abrasion and can be worn-outed due to interlamination crack as the speed increased. [ ·¢×ÔÊÖ»ú°æ https://muchong.com/3g ] |

ÒÔϽö¹©²Î¿¼£º 1. The coating is compact and the microstructure of both coatings is dominated by ¦Ã-Al2O3 and contains some amorphous 2. Both coatings have excellent anti-skidding property 3. Both coatings demonstrate excellent wear resistance. At low speed the coating failure mechanism is dominated by grain being pulled out while with increased speed, layer stripping due to interlaminal crack propagation is the main cause of coating wear failure. ½ö¹©²Î¿¼ |
