Description

При получении металлокерамических сплавов мели или ссрсора с 0,1-30% кадми  известными способами неизбежны большие потери кадми  в результате его испарени  в процессе снекапи  сплавов.When metal-ceramic alloys are obtained by means of a chalk or sssor with 0.1–30% cadmium by known methods, large losses of cadmium are unavoidable as a result of its evaporation in the process of snekapi alloys.

В предлагаемом способе потерп кадми  в процессе спекани  таки.х сд/лавов Ясутствуют благодар  тому, что спекаппе проводитс  прп повышенном давлении (от 3 до 150 ата) защитного газа в засыпке, состо щей из смеси порошков тугоплавкой окиси металла и окиси кадми  {или кадми ), содержащей 0,5-10°ь кадми . При этом обеспечиваетс  получение более однородных по .химическому составу сплавов.In the proposed method, cadmium tolerance during sintering of these. X sd / lavas are present due to the fact that the spekappa conducts an increased pressure (from 3 to 150 atm) of protective gas in the charge consisting of a mixture of powders of refractory metal oxide and cadmium oxide ) containing 0.5-10 ° c cadmium. In this case, a more homogeneous chemical composition of the alloys is obtained.

По описываемому способу сплавы типа медь-кадмий и серебро-кад .мий изготавливаютс  путем порошков эти.х металлов в соотношении , необ.ходимом дл  нол чепи  сплавов заданного состава. Из смеси порошков прессуютс  заготовки изделий. Давлешю прессовани  выбираетс  в пределах от 3 до 8 т/см- в зависимости от требуемой плот пости издели . Прессованные заготовки помещаютс  в лодочки из кера .микн или жаропрочного сплава и засыпаютс  смесью порошков окнси алюмини  и м еталличеекого кадми  пли окиси кад.мн . Чтобы в процессе спекани  не происходило изменени  состава спекаемого сплава, засыпка должна содержать от 1 до 20% окиси кадми  или от 0,5 до металлического кадми , остальное - окись алюмини  или двуокись титана . Более точные пределы содержа(П1  кадмиевого компонента в за сыпке подбираютс  экспериментально.According to the described method, copper-cadmium and silver-cadmium alloys are manufactured by powders of these metals in the ratio required for the chain of alloys of a given composition. From the mixture of powders, blanks are pressed. The pressing pressure is chosen in the range from 3 to 8 t / cm, depending on the desired density of the product. The pressed billets are placed in boats of mixed or high-temperature alloy and poured with a mixture of oxy-aluminum powders and more cadmium or cadm oxide mn. In order to not change the composition of the sintered alloy during sintering, the backfill must contain from 1 to 20% cadmium oxide or from 0.5 to metallic cadmium, the rest is alumina or titanium dioxide. More accurate limits containing (P1 of the cadmium component in the grating are selected experimentally.

Лодочки с издели ми помещаютс  в автоклав, где они нагреваютс  в атмосфере защитного газа до заданной температуры, выдерживаюте  р течение времени, необходимого дл  проведени  процесса спекани , и охлаждаютс  до комнатной температуры, после чего навлекаютс  из автоклава . Давление газовой среды в автоклаве во вре.м  нагрева, выдержки и охлажде п(  пзделгпн 1одлерживаетс  не ппже 3 ата. )моThe boats with products are placed in an autoclave, where they are heated in a protective gas atmosphere to a predetermined temperature, allowed to stand for a period of time required for the sintering process and cooled to room temperature, after which they are drawn from the autoclave. The pressure of the gaseous medium in the autoclave in times of heating, holding and cooling n (pdegler 1 is not supported by 3 am.)
