一、前言鳞爆是搪瓷制品的一种严重缺陷。这种缺陷往往是在搪瓷烧后几天,甚至几个月才在搪瓷层内产生。缺陷大小不等,厚度不均,多为一端厚,一端薄,颇似鱼鳞,有时只损坏瓷层表面,有时则直通金属,呈半月形巢穴,人们将此种搪瓷层的剥落称为鳞爆,又称冷爆。 Shaw于1920年就提出鳞爆是由聚集在搪瓷层下的气体引起的;Sasse于1925年观察到这种缺陷,并指出其根源是氢;Viehber于1930年第一次明确提出鳞爆是由氢造成的,现已为人们所公认。通常认为在搪烧温度下,扩散到钢铁中的原子氢,被吸附在晶界,晶格畸变区,铁索体与渗碳体之间的相界以及非金属夹杂物
First, the foreword Scale explosion is a serious defect of enamel products. This defect is often in the enamel burning a few days, or even months before the enamel layer. Defects ranging in size, uneven thickness, mostly thick at one end, thin at the end, like a fish scale, and sometimes only damage the surface of porcelain, and sometimes straight through the metal, was a semilunar nest, people will such exfoliating enamel layer called squamous explosion , Also known as cold burst. Shaw suggested in 1920 that the squiggle was caused by gas gathering under the enamel layer; Sasse observed this defect in 1925 and pointed out that the root cause was hydrogen; Viehber first explicitly proposed in 1930 that the squally detonation was caused by Hydrogen caused, now recognized by people. It is generally considered that atomic hydrogen diffused into steel at the sintering temperature is adsorbed at the grain boundary, the lattice distortion region, the phase boundary between the ferrite body and the cementite, and the nonmetallic inclusions
