surface quenching meaning in English
表面淬火
Examples
- Effects of comprensive technological parameter to laser surface quenching of common steel and iron
综合工艺参数对常用钢铁材料的激光淬火特性的影响 - Sf - gp - cyp - iii mainly used for surface quenching , welding , metal powder sintering tube seam annealing and metal parts heat penetrating
主要用于钢铁机械零件的表面淬火钎焊粉末金属的烧结，钢管焊缝的退火，以及金属部件的透热等。 - The activation effect of zn2 + modification , including enhancement of emission intensity , slowing of luminescence decay and increasing of quantum yields , results from the formation of zns shell outside the nanoparticles , which is passivating the surface of nanoparticles , eliminating the surface quenching centers , so as to block the nonradiative transition pathways through these kind of quenching centers
Zn ~ ( 2 + )表面修饰在纳米颗粒表面形成了zns壳层，钝化了纳米颗粒的表面，消除了表面猝灭中心，阻塞了通过表面猝灭中心进行无辐射跃迁的通道，从而使得发光强度增加，衰减变慢，量子效率提高。 - Induction heated oil tempered spring wire is a kind of new technical material which has been developed since 1980s . it can be heated by means of eddy induced into itself through electromagnetic coil and this method is mainly used in surface quenching . with correct designing and reasonable current frequency , induction coil and heat treatment process selected , as well as plc controlling applied , the wire can be uniform heated along cross - sectional and longitudinal direction and can be quenched and tempered continuously
应加热油淬火-回火弹簧钢丝，是二十世纪八十年代发展起来的新技术材料，在国外称为itw induction heat oil tempered spring wire 。是通过线圈电磁感应钢丝本身产生的涡流进行加热，通常主要用于表面淬火。经正确设计，选择电流频率，合理的感应线圈及热处理工艺，并实施plc控制，可使钢丝整个截面及长度上得到均匀加热，进行连续整体淬火和回火。 - Strengthening mechanism of ion nitriding is different from surface quenching and cementation , which makes surface strengthen by quenching to get martensite . ionic nitriding is the way to make materials strengthe n , which result from the steady compound formed on the surface of the metal . there is no need for quenching after treatment
离子渗氮的强化机理不同于表面淬火，渗碳等表面热处理方法，这些方法必须进行淬火得到马氏体使表面强化，而离子渗氮是在金属表面形成稳定化合物而使材料强化，处理后不须淬火。
