Description

В качестве солей т желых металлов могут быть использованы соли различных органических и неорганических кислот.As salts of heavy metals, salts of various organic and inorganic acids can be used.

Введение солей т желых металлов позвол ет в любой последовательности травить титан и сплавы титана, включа  легированные благородными металлами; скорость травлени  будет зависеть лишь от степени выработки раствора, что весьма важно в производственных услови х.The introduction of heavy metal salts allows etching titanium and titanium alloys, including those alloyed with noble metals, in any sequence; The etching rate will depend only on the degree of solution production, which is very important in a production environment.

В табл. 2 приведен один из примеров, подтверждающих это положительное качество .In tab. 2 shows one of the examples confirming this positive quality.

Кроме того, введение солей т желых металлов позвол ет увеличить производительность травильной ваины на 25-30%, улучшить санитарно-гигиенические услови  труда.In addition, the introduction of heavy metal salts makes it possible to increase the productivity of etching vain by 25–30%, and to improve the sanitary and hygienic working conditions.

Примечание: а)-сплав титана 4200, б)-титан BTI-0.Note: a) titanium alloy 4200, b) BTI-titanium.
