Njirimara ịgbado ọkụ dị iche iche ọla kọpa alloys

Njirimara ịgbado ọkụ dị iche icheọla kọpa alloys:

1. The thermal conductivity nke ọla kọpa na-acha uhie uhie dị elu.Nrụpụta ọkụ nke ọla kọpa na-acha uhie uhie n'ime ụlọ dị ihe dị ka okpukpu 8 karịa nke ígwè carbon.O siri ike ikpo ọkụ welded ọla kọpa n'ime mpaghara ka ọ na-agbaze.Ya mere, ekwesịrị iji isi iyi ọkụ nwere ike gbadoro anya n'oge ịgbado ọkụ.Mgbawa na-emekarị mgbe a na-agbakọta ọla kọpa na ọla kọpa.Mgbawa dị na welds, ahịrị ngwakọta na mpaghara okpomọkụ metụtara.Ihe mgbawa ahụ bụ mmebi intergranular, na agba oxidation doro anya nwere ike ịhụ site na ngalaba obe.N'oge usoro ịgbado ọkụ, chọpụta oxygen na ọla kọpa na-etolite Cu2O, wee mepụta eutectic dị ala (α+Cu2O) nwere ọla kọpa α, ebe mgbaze ya bụ 1064°C.

2. Lead bụ ihe a na-adịghị ahụkebe na ọla kọpa siri ike, na ndu na ọla kọpa na-etolite eutectic dị ala nke nwere ebe mgbaze nke ihe dịka 326 ° C.N'okpuru omume nke ịgbado ọkụ esịtidem stress, ọla kọpa na ọla kọpa alloy nkwonkwo na elu okpomọkụ ụdị cracks na-emebi emebi akụkụ nke welded nkwonkwo.Na mgbakwunye, hydrogen na weld nwekwara ike ime ka mgbawa.Porosity na-emekarị na welds nke ọla kọpa na ọla kọpa alloys.Ọ bụ hydrogen gas na-ebute porosity dị na ọla kọpa dị ọcha.Mgbe ikuku CO na-agbaze na ọla kọpa dị ọcha, ọ pụkwara ịkpata pores site na ikuku mmiri na CO2 gas na-emepụta site na mmeghachi omume nke carbon monoxide na oxygen.

3. The porosity guzobe ọchịchọ nke ọla kọpa alloy ịgbado ọkụ bụ nnọọ ibu karịa nke dị ọcha ọla kọpa.N'ozuzu, a na-ekesa pores na etiti nke weld na nso eriri njikọ.Mgbe a na-agbakọta ọla kọpa dị ọcha na ọla kọpa, ihe eji arụ ọrụ nke nkwonkwo na-ebelata.Na usoro ịgbado ọkụ nke ọla kọpa alloys, ọla kọpa oxidation, na evaporation na ọkụ nke alloy ihe ga-eme.Ebe eutectic dị ala na-agbaze na ntụpọ ịgbado ọkụ dị iche iche na-eduga na mbelata ike, plasticity, nguzogide corrosion na eletriki eletrik nke nkwonkwo welded.
