The surface is yakeli get together fat of third acerbity armour the reverse side uses colophony gesso to add fibre glass in order to enhance its hardness.
亚克力表面为聚丙酸甲脂，背面采用树脂石膏加玻璃纤维，以增强其硬度。
The diffusion zone width of main alloying elements increases and hardness of the friction weld zone near TC4 titanium alloy side improves after post-weld heat treatment.
经焊后回火热处理后，主要合金元素沿焊合区的扩散区宽度增大；焊合区钛合金侧硬度值显著提高。
However, because of fully granin refinement of martensite and good perfornance of temper resistance , the hardness of outer surface of worn side is equal to that of non-worn side.
而最表层由于获得完全细化的马氏体组织，拥有较好的回火稳定性，与未偏磨面表层硬度相当。
The hardness of the reverse side is harder than the right side, because it have an advantage in small crystal of random direction.
后者被认为由于随机取向的微小晶粒占优势，其硬度比生长面略高。
