Increase wet liner on nitrogen treatment layer
2015
The utility model provides an increase wet liner on nitrogen treatment layer, including the cylinder jacket, there is the nitrogen treatment layer to cover at the water jacket position in the cylinder jacket outside, the axial length L1=90~150mm on nitrogen treatment layer, the 0.01~0.10mm of thickness on nitrogen treatment layer. Cylinder jacket diameter D=100~120mm, 1 length L=190~290mm of cylinder jacket, water jacket the wall thickness T=4~10mm of cylinder jacket. The utility model discloses a there is the cover of nitrogen treatment layer at the water jacket position, and the toughness of matrix is high, can reduce the probability of surface crack's formation and extension, and anti wear resistance is good, and corrosion resistance is good, and the surface is fine and close, and the composition is stable, is difficult for taking place the reaction with materials such as acid, alkali, salt, can improve the ability of losing in the corrosion -resistant and anti cave of cylinder jacket effectively. The reliability verification has been passed through on 8~10 liters of diesel engines. Can be applied to various engines, including diesel engine, gasoline engine and gaseous engine etc..
