THE ANALYSIS OF CRACKS ON THE FORM SPRING COIL |
|
|
|
Abstract Cracks on the disc spring parts and raw materials, using metallographic examination, chemical analysis, hardness testing, scanning electron microscope by means of a comprehensive analysis of results showed that: raw materials, sulfides are more processed into disc spring, after the formation of many defects in its surface , phosphating, pickling after the defects generated at hydrogen corrosion, cracks generated when the force a long time.
