这是客户给出的技术要求。由于水平有限我翻译的不太准确。
Description:
描述:
A low temperature pit furnace orientated nitrocarburising process which offers the engineer a viable alternative to classical gaseous nitriding
低温热炉氮碳共渗工艺为主的工程师提供一个可行的选择古典气体氮化
Application:
应用:
The process is applied to alloy steel components which would normally be nitrided.it should be noted that the process has two main advantages over the traditional process.
这个过程是适用于合金钢部件通常将氮化。应当指出的是,这一进程有两个主要优势的传统工艺。
1 the process replaces the brittle and undesirable white layer associated with nitriding with a more flexible compound layer which does not need to be removed before going into service.
1进程取代脆性和不可取的白层与渗氮,以更加灵活的化合物层并不需要删除再进服务。
2 process turn-round time is reduced by some 60%
2进程反过来轮的时间减少了约60 %
Typical components:crankshafts,gears,camshafts,cylinders,seat slides.
典型的组成部分:曲轴,齿轮,凸轮轴,缸,座椅幻灯片。
Metallurgical aspects:
冶金方面:
