电解加工时零件的表面层发生极其重要的变化,它对被加工材料的疲劳抗力有着显著的影响。由于疲劳强度的降低,因此有必要把受影响的表面层除去。本文旨在研究用手工抛光法来恢复材料的疲劳强度的可能性,并确定在电解加工以后,为了达到原有疲劳极限必须除去的最小厚度。试件是由下列材料制成的:结构钢40XHMA和30、钛合金BT8以及耐热合
Electrolytic processing of the surface layer of the parts of the extremely important changes that have been processed materials fatigue resistance has a significant impact. Due to the reduced fatigue strength, it is therefore necessary to remove the affected surface layer. This paper aims to investigate the possibility of restoring the fatigue strength of a material by hand polishing and to determine the minimum thickness that must be removed in order to reach the original fatigue limit after electrolytic processing. The test piece is made of the following materials: structural steel 40XHMA and 30, titanium alloy BT8 and heat-resistant
