Requirements for surface treatment of corrugated washers

date:[2015-01-05]     pk_hits:

The surface of the waveform washer needs to undergo oxidation blackening treatment to ensure that the surface is free from defects such as defects and oxidation rust. At the same time, the waveform distribution of the waveform washer should also be uniform. Due to its shape characteristics such as thin wave thickness and elasticity, the waveform washer has certain difficulties in feeding and accurately assembling in place. Because the corrugated washer is composed of several peaks and valleys, the thin circular elastic metal component is made of high-quality spring steel, which has been heat treated by specific methods and the hardness is generally controlled between HRC44-55 according to specific circumstances, with good elasticity.

The reasons for the continuous early fracture on the surface of corrugated washers during use were analyzed from the aspects of chemical composition, microstructure, fracture morphology, hydrogen content, hardness, etc. Hydrogen embrittlement and tempering embrittlement verification tests were conducted on the same batch of parts to analyze the effects of hydrogen removal time, hydrogen content, hardness, and tempering temperature on the fracture morphology. At the same time, the influence of different hardness testing methods on the hardness value of waveform washers was analyzed.
