据美国恩赫脱、瓦斯报导,热处理缺板材可用水玻璃防止(骨葬)污,可使热处理的准备时间从30小时缩短到1小时。在升高温度下,钛能被炉氛强烈(骨葬)污,因此在加热时防止钛表面与外界接触而涂上一层保护层的方式是必须的。最初的保护层是用铝硅作涂料,这就须要很长一段干燥时间,而且在放久炉中之前操作要仔细,且热处理后很难除去这一层涂料。
According to Enkhoff in the United States, the gas reported that the heat-treated panels could be protected by water glass to reduce the heat treatment preparation time from 30 hours to 1 hour. At elevated temperatures, titanium is strongly fouled by the atmosphere and therefore it is necessary to coat the surface of titanium with a protective coating during heating. The initial coating is aluminum-silicon coating, which requires a long period of drying time, and long before operation in the furnace to be careful, and it is difficult to remove the coating after heat treatment.
