The valve axis adopt stainless steel, it has good abradability and anti-causticity.
After nitriding, the abradability of the boring axis is increased greatly.
So abradability is one of the important factors to choose prosthetic material.
This article analyses influence of heat setting process on abradability and permeability of batt-on-mesh needled felt.
Aluminum material be aluminized level abradability poor prone to scratching, densed surface is damaged.
The pressure screwpairs need to meet the demanding of intensity, rigidity, abradability and stability.
In addition, surface coating will increase the ink abradability, especially covered entirely by the ink object.
