Argon ịgbado ọkụ nke aluminum: ihe bụ mgbagwoju anya nke

The nke nke kasị dị ụzọ ịgbado ọkụ nke aluminum dị ọcha ụdị ya dị iche iche alloys nnọọ mkpa na njikọ na ha sara mbara ngwa. Otu n'ime ndị nkịtị teknụzụ atụle argon ịgbado ọkụ nke aluminum. A welded netermouprochnyaemye deformable aluminum alloys nke teknuzu aluminum (akara AD AD1) dabere na aluminum alloys na manganese (AMts), aluminum na magnesium (AlMg). Dị otú ahụ alloys ọkacha mma na-agụnye ike-ka. N'ihi na ha na-eji, ma ọ bụrụ na okpomọkụ omume bụ omume maka Ọdịdị.

Alumina akpụ refractory film n'elu nke workpiece (TM Al ₂ O ₃ = 2050 ° C), na-enwe a ukwuu njupụta karịa metal onwe ya. Na mbibi nke ndị na oxide film nke ya ahụ merụọ welded saa, nsogbu njikọ n'ọnụ ya. Ya mere argon ịgbado ọkụ nke aluminum mma mgbe n'ibu oxide mwepụ ma ọ bụ etching isi na dịanyā ọla.
