nitrided layer
基本例句
渗氮层
The result shows that the porosity ofnitrided layeris due to the over concentration of CNO- in the salt bath.试验结果表明，渗层疏松主要是由于盐浴内CNO－浓度过高所致；
This paper deals with the kinetics of the ionnitrided layergrowth for armco iron, steels 45, 40Cr, 42CrMo and 38CrMoAl.本文研究了在不同离子渗氮工艺参数下,纯铁、45钢、40Cr、42CrMo及38CrMoAl钢等五种材料的离子渗氮层长大动力学,建立了长大动力学的数学模式。
Recent progress is presented regarding the research of structure, process, property, failure and strengthening mechanism of the composite “nitrided layerPVD coating”.摘要介绍了“渗氮／物理气相沉积”复合涂层在涂层结构设计、工艺与性能、失效与强化机制等方面研究的最新进展。
It is proposed that cooling ways greatly influence the hardness ofnitrided layer,and the content of CNO - within the range of fluctuation has little effect.发现盐浴渗氮层的硬度受冷却方式的影响很大 ,而CNO-浓度在一定范围变化则影响很小 ,钒的渗入有利于改善渗层硬度。
The hardness gradient, depth , microstructure and phases of nitrided layers were measured with Microhardness Apparatus, Microcopy and X-ray diffractometer .利用显微硬度计、金相显微镜和X射线衍射仪测定了渗氮层的硬度梯度、层深、显微组织和相组成。 |
