由于拖拉机机组功率和工作速度的增大,传统的强化方法已不能保证对耐磨性的日益增长的要求。使零件的工作表面获得专门的耐磨覆盖层,是大大地提高耐磨性的有效方向。有多种多样的办法可以获得这些覆盖层,其中最有前途的是在真空中获得覆盖层的方法。 有一种在真空中在离子轰击下由等离子相沉积而获得覆盖层的新方法,简称。 按照这种方法获得覆盖层的过程包括两个 Due to the increase of tractor unit power and working speed, the traditional reinforcement methods can no longer guarantee the increasing requirement of wear resistance. The part of the work surface to obtain a special wear-resistant coating, is greatly enhance the effective direction of wear resistance. There are a variety of ways to get these overlays, the most promising of which is the way to get overlays in a vacuum. There is a new method of obtaining a blanket by plasma deposition in vacuum under ion bombardment, abbreviated. The process of obtaining the cover according to this method includes two
