This helps to reduce crack propagation, etc and does teh same kinda things as dlc, less friction = less heat= less power loss= less wear on parts. But this also helps gear meshing and oil drag etc. Both very expensive processes to get done. The other one is cryogenic processing the components. < that one makes dlc and superfinishing look cheap.
Thank you kind sir! Awesome info
