Abstract
A wear-resistant coating with a low friction coefficient of aluminum titanium nitride-tungsten disulfide (AlTiN—WS2) and a preparation method are provided. The preparation method includes: (1) performing a titanium ion cleaning on a preprocessed substrate by using a titanium ion arc target to obtain a cleaned substrate; (2) depositing a titanium transition coating on the cleaned substrate by using a multi-arc ion plating to obtain a deposited substrate; (3) depositing an aluminum titanium nitride (AlTiN) coating on the deposited substrate by using an AlTi alloy ion arc target to obtain an AlTiN coating substrate; and (4) depositing a titanium coating and a tungsten disulfide (WS2) coating by using a high power impulse magnetron sputtering (HiPIMS) to obtain the wear-resistant coating of AlTiN—WS2. The wear-resistant coating is prepared by pre-depositing the AlTiN solid coating using the multi-arc ion plating, and followed by depositing the WS2 solid lubrication coating using HiPIMS.
