摘要

主要研究20碳钢表面经过碳-氮共渗热处理后在250℃~500℃的温度范围内受飞灰磨损的规律。试验结果表明

经过表面碳-氮共渗热处理后的20碳钢在试验温度范围内

仍然具有未处理时的热态磨损规律

即随温度的升高

相对磨损量先减小而后增大

临界温度为331℃。20碳钢经C-N共渗后相对磨损量减小一倍左右。

Abstract

The regularity of fly ash erosion on the surface of 20 carbon steel after heat treatment of carbonitriding

in a temperatre range of 250 ℃～500 ℃

has been mainly studied

results show that the 20 carbon steel after surface heat treatment by carbonitriding still has hot state erosion regularity before said treatment in the test temperature range

i.e.along with the temperature rise

the relative erosion rate decreases at first

and then increases

the critical temperature to be 330 ℃.After carbonitriding

the relative erosion rate of 20 carbon steel decreases about a half.
