1. About the technology
Due to the characters of material, the working depth of Ultrasonic Surface Process Equipment is from 0.1um to 1mm, with a surface smoothness of 0.02um and a 100um deep nanocrystal surface.
Seen from the processed materials such as Ti alloy, 40Cr, No.45 Steel and Al alloy, the equipment show its great effort. For instance, after processing, 40Cr gets a 0.15um surface smoothness and a 60um-deep surface nanocrystal.

4. Surface Hardness Analysis
a. No.45 Steel
From the picture below we can see that, after processing, there is a apparent rise on the surface hardness while the further from surface ,the smaller the hardness is. Compared with the inner part, the surface hardness increases by 1 time and up to 200um deep part is enhanced.
b. 40Cr
Compared with the inner part, the surface hardness increases by 3 time and up to 100um deep part is enhanced apparently.
