Abstract : the working principle , structure and parameters design of plasma arc generator for heat treatment are described . experiment has shown that it has good effect on partial surface hardening 文摘:论述了用于金属材料表面热处理的等离子弧发生器的工作原理、结构特点和参数设计。试验证明这种发生器对材料的表面局部硬化非常有效。
In heat treated shandong sapphires , the micro - crackes are more devoloped , and scattering of structural micro - inclusions to light are probably one of reasons why heat treatment on shandong sapphire is not effecient 经热处理的山东蓝宝石中微裂隙更为发育，这些结构类微细包裹体对光的散射作用可能是山东蓝宝石热处理效果不佳的原因之一。
Abstract : in this paper , the principle of laser transformation hardening ( lth ) is introduced , what lth who raises life of metallic materialc is aimed at is discussed , and then we study the mechanism to enhance life of metallic matrerials 文摘:介绍了激光热处理的原理，并讨论其提高金属材料寿命的针对性，进而研究激光相变硬化提高材料寿命的机理。
It has exact processing and heat treatment gate bushing , the part of heat can be delivered to the steel around the gate which make the plastic just enter wouldn ' t be frozen so quickly . it applies to crystalline materials 带精确加工及热处理的一体浇口司，能传递部分热量至浇口区域的金属，使得刚一进入型腔的塑料不至于迅速凝固，适于快速凝结的结晶性塑胶。
The contact angle with water is 64 ? for the thin film without annealing . after 650 ? annealing treatment , the contact angle becomes 0 . with proper sno2 doping , the hydrophilicity of tio2thin film will be also improved ( 3 )没有经过热处理的tio _ 2薄膜与表面水滴的接触角为64 ，经过650热处理后薄膜与水滴的接触角为0 ，掺杂sno _ 2对tio _ 2薄膜的亲水性有所改善。
The purpose of the paper is to search the feasibility of the ecletron - beam weld of ti3al intermetallics and tc11 ( a + b ) two phase titanium alloy , and the influence to weld microstructure and properties of the hot deform and heat treatments 本文的目的是探索ti _ 3al金属化合物tac - 1b合金与tc11两相钛合金电子束焊、热模锻及热处理的可行性，并研究焊后热加工变形与热处理对组织与性能的影响。
The influences of the compositions and heat treatment temperature on the refractive index of sio2 - zro2 gel glasses were also investigated . after treated at 150 , the refractive index of sio2 - zro2 gel glasses could be adjusted in the range of 1 . 438 - 1 . 546 by altering the zr content 经150oc热处理的5102一zro :二元系统凝胶玻璃，其折射率可因zro :含量的改变，实现在1 . 438一1 . 546范围内调控。
At the same time , the experience of hot processing of mh alloy shows that , the key factor determine the oxidation of alloy were the amount of hydrogen during hot processing and the cool state when the alloy come out of the hydrogen atmosphere 在热处理的过程中,通入还原气体氢气的量及电极离开还原气氛是否完全冷却的状态都对热处理有着较大的影响。主要是要保证在整个热处理的过程中电极不被氧化。
