以氢作保护介质生产钛合金优质铸件氢在钛中的溶解具有可逆特性，溶解度随反应温度的提高而急剧下降。这就可以将氢作为保护介质生产钛合金的优质铸件。在金属—铸型界面上建立氢保护气氛，这可由含氢钛粉末来实现；把以氢化钛粉末为基的悬浮液涂于铸型的工作表面，通过铸...
Hydrogen as a protective medium for the production of high-quality titanium alloy castings have reversible hydrogen solubility in titanium, the solubility decreases sharply with the increase of the reaction temperature. This makes it possible to produce high-quality titanium alloy castings using hydrogen as a protective medium. A hydrogen protection atmosphere is established at the metal-mold interface, which can be achieved by hydrogen-containing titanium powder; the titanium hydride powder-based suspension is applied to the working surface of the mold by casting ...
