die burn meaning in Chinese

烧伤(焊接缺陷)

Surface hardness is strengthened by use of plasma nitriding technique to change microstructure of mould surface . on the basis of that , the major research works accomplished in this paper are as follows . hardness , resistant attrition , fatigue strength , resistant erode and resistant die burn of the materials are enhanced and the life of the mould is increased by five to ten times
本人根据近年来模具工业的快速发展，模具的表面工程越来越受到普遍重视，利用等离子渗氮技术可以改变模具表面的组织结构使表面硬度得到强化，提高了材料的硬度、耐磨性、疲劳强度、抗腐蚀能力及抗烧伤性，使模具的寿命提高5 - - 10倍。
It is these particles that can change nitriding layer microstructure and that accelerates the layer formation . nitrogen is infiltrated through the surface of metals and it changes the chemical components . as a result , the surface of metal has good performance with high hardness , high resistant attrition , high fatigue strength , high resistant erode and resistant die burn
这些高能粒子可以改变渗层组织，结构和促进化学反应过程，加速渗层形成，使氮元素渗入金属表面，从而改变金属表面的化学成分，使之具有高硬度、高耐磨性、高疲劳强度、高腐蚀能力及抗烧伤性。
