Furthermore, the surface of the arc-shaped groove is provided with an impact-resistant coating, and the impact-resistant coating is a Cr-DLC coating.
In the invention, the Cr-DLC coating is a chromium-diamond-like carbon-based coating, and the diamond-like carbon-based (DLC) coating has gained more attention and research in the fields of machinery, cutters, aerospace and the like due to the excellent performance and characteristics thereof. However, the traditional DLC coating has the defects of higher internal stress and poor toughness, so that the deformation between the coating and a substrate is difficult to coordinate, and the partial peeling occurs, thereby leading to the failure of the coating. Through researches, doping certain elements in the preparation process of the DLC coating can obviously reduce the residual stress of the coating and improve the binding force with a substrate. When Cr is used as doping element, the high stress and brittleness of DLC can be improved, and the friction and wear resistance can be further improved. The invention adopts an impact abrasion tester with impact kinetic energy as a control condition in the prior art, and researches impact abrasion behavior and characteristics of Cr-doped diamond-like carbon (Cr-DLC) coating through dynamic response and evolution of energy absorptivity. Experiments show that the grinding mark surface layer of the Cr-DLC coating has a small amount of micron-sized peeling, has no friction oxidation behavior, and has excellent shock resistance. The Cr-DLC coating can obviously improve the service stability and the service life of the press block.
