根据氢化钛用于粉末冶金烧结能防止氧化的原理,我厂将氢化钛用于高温钎焊,简化了氢气保护的高温钎焊工艺,质量稳定,效果良好。氢化钛是具有吸附气体能力的一种金属钛的吸附物。一般来说,一克钛在室温时可吸附407毫升氢,温度上升时,其吸附程度下降,在1000℃时,只能吸附66毫升氢。钛除了吸附氢以外,还和氧、氮等化合,生成稳定的化合物。吸附了氢的氢化钛,在900℃以上时大量释放原子态氢[H],这种氢[H]不但具有理想的保护作用,而且具有强烈的还原能力。钛的氧化物和氮化物,在此温度下仍然很稳定。这
According to titanium hydride for powder metallurgy sintering can prevent oxidation principle, I plant titanium hydride for high-temperature brazing, simplifying the high-temperature brazing hydrogen protection process, the quality is stable, the effect is good. Titanium hydride is a metal titanate adsorbent that has the ability to adsorb gases. In general, one gram of titanium can adsorb 407 ml of hydrogen at room temperature. When the temperature rises, the degree of adsorption decreases. At 1000 ° C, only about 66 ml of hydrogen can be adsorbed. In addition to adsorption of titanium in addition to titanium, but also with oxygen, nitrogen and other compounds, generating stable compounds. Hydrogen-adsorbed titanium hydride releases a large amount of atomic hydrogen [H] when it is above 900 ° C. This hydrogen [H] not only has an ideal protective effect but also has a strong reducing ability. Titanium oxide and nitride, at this temperature is still very stable. This
