Method for producing porous titanium sinters from titanium based titanium alloys or composites in the process of magnesium dealloying

摘要

the subject of the invention is a way to produce porous sinter titanium (titanium based, titanium alloys and titanium based composites on) by thermal process ofthe magnesium.method of manufacturing porous sinter of titanium, titanium alloys or titanium based composites on the odstopowania magnesium is suchthe powders of magnesium and titanium and other possible alloying additives (ta, nb, zr, mo, si, fe, al, v) in proportions incorporating density or volume of 30 - 70%, preferably 50 mas mas.% is subjected to mechanical process synthesis in a protective atmosphere of argon controlled oxygen content and water level. 1 ppm, by weight to the weight of the powder mielniku00f3w minimum 10,preferably 20, during 8 - 10 hours, preferably by 10 hours, then alloy powder is pressed under pressure of 500 - 1000 mpa, preferably 1000 mpa.then wypraski undergo spiekaniu while process odstopowania in temperature above boiling temperature magnesium, 1200 - 1300u00b0c, favourably 1300u00b0c within 1 to 5 hours.preferably 2 hours in a vacuum; then cooling sinters with stove.
