  • Patent number: 7458158
    Abstract: This invention introduces a new category of engineered surfaces and corresponding production processes for better wear resistance and lower friction loss. The structured surfaces can be applied on many automobile components with frictional surfaces. The composite structure settles the usual conflicts between surface functions and stresses. Two sets of multiple-step processes are introduced to achieve high production efficiency and low cost. Unlike traditional surface technologies that generate single and uniform layers on the whole part surface, the new technology processes the part surface selectively for more effective surfaces with versatile functions.
