1) nitrided layer
渗氮层
1.
The results show that,the thickness of nitrided layer was 0.
结果表明,经淬火+二次回火和淬火+三次回火的试样渗氮后,渗氮层厚度均达到约0。
2.
The results show that the major reason for the lower contact fatigue strength of the nitrided part is that nitrided layer is very thin and the shearing stress is resisted by lower strength zone(transition zone) of the nitride layer when a heavy load is borne by the part,therefore the nitrided part has lower contact fatigue strength and high hardness.
分析表明:渗氮件接触疲劳强度不够高的主要原因是渗氮层厚度太薄;在重载荷条件下,是靠低强度区(过渡区)抵抗接触疲劳破坏,故渗氮件硬度虽很高,但接触疲劳强度却不很高。
3.
The element was analyzed by means of metallographic examination and microhardness measurement The result showed that the microhardness was too low and the nitrided layer was too shallow after nitriding process.
结果表明:导致零件失效的主要原因是渗氮后零件的硬度太低,渗氮层深度较浅所致。
2) nitriding layer
渗氮层
1.
The research indicated that the granular bainite present in the 38CrMoAlA steel would result in formation of brittle acicular nitrides in the nitrided case,and thus surface of the nitriding layer would exfoliate.
着重研究了38CrMoAlA钢中粒状贝氏体对渗氮层组织和性能的影响,指出,粒状贝氏体的存在会使氮化层表面形成脆性针状氮化物,导致渗层表面发生剥落。
2.
Based on the plasma nitriding technology,the effect of temperature on the microstructure and properties of plasma nitriding layer of 3Cr13 stainless steel was studied.
利用等离子渗氮技术,在不同温度下对3Cr13不锈钢渗氮6 h,研究了渗氮温度对渗氮层组织结构和性能的影响。
3) nitrided case
渗氮层
1.
The results revealed that the denitriding would cause decrease in hardness of the nitrided cases of all tested steels in varying degresses,with the decrease in hardness of 38CrMoAl steel being the smallest.
对不同钢渗氮层在高于590℃不同温度退氮处理,然后测定其组织和性能的变化,结果表明,退氮处理后,所有试验钢的渗氮层硬度均有不同程度的下降,以38CrMoAl钢硬度下降最少,但表面有网状裂纹,再重新渗氮硬度不可能恢复;不锈钢经退氮处理可降低渗氮层脆性,增加渗层深度。
4) nitride
