Mgbe ịzụrụmagnesium alloyihe ma ọ bụ machining a ogbe nke magnesium alloy ngwaahịa, ma ọ bụrụ na ị chọrọ na-echekwa ha, a na-atụ aro na-arụ ọrụ dị mma nke mgbochi nchara ọgwụgwọ na ihe na ngwaahịa iji gbochie oxidation na-emetụta emecha ojiji.
Iji gbochie ihe ndị magnesium na-emetọ ma ọ bụ mebie n'oge njem na nchekwa, ngwaahịa ndị a na-edozi n'elu ma gafere nyocha ahụ kwesịrị ịbụ mmanụ na ngwugwu n'ime awa 48. Tupu iji ihe magnesium alloy, a ga-ewepụ ihe mkpuchi nchebe nke mmanụ nchara, n'ihi ya, a na-achọ mmanụ na-egbochi nchara ka ọ nwee ihe magburu onwe ya na-eme ka nchara, dị mfe ịkwanye ma wepụ mmanụ. Ya mere, a na-ejikarị oyi akwa mmanụ mgbochi nchara. A na-agbakwunye ihe dị iche iche na-egbochi corrosion dị ka pasta wax oxidized, sulfonates mmiri, acid fatty, esters, soaps, wdg na mmanụ ịnweta mmanụ, nke a na-ejikarị dị ka mmanụ mgbochi nchara maka magnesium alloys. Ihe na-egbochi corrosion na-eme ka ihe nkiri polymer na-eme ka hydrophobic corrosion na-egbochi ihe nkiri na kọntaktị nke mmanụ na ígwè, nke na-arụ ọrụ nchebe.
Magnesium alloys dị mfe na corrosion n'okpuru ọnọdụ eke. Na mgbakwunye na usoro nke itinye mmanụ nchara, ekwesịrị itinye uche na isi ihe ndị a n'oge eji, nchekwa na nchekwa:
1. Magnesium alloys ekwesịghị ikpughe na ikuku iru mmiri ruo ogologo oge, na mmiri ozuzo na foogu ka amachibidoro;
2. Mgbe ị na-echekwa magnesium alloys, a machibidoro iwu ozugbo ịkpọtụrụ acid, alkalis na salts;
3. Iru mmiri nke ụlọ nkwakọba ihe na-echekwa ihe magnesium ekwesịghị gafere 75%, na okpomọkụ ekwesịghị ịgbanwe nke ọma;
4. N'oge njem, a ghaghị mechie elu nke magnesium alloy ma kpuchie ya iji gbochie mmiri. Ọ bụrụ na ahụrụ nchara dị nro, a ga-ehichapụ ya ozugbo, na-ekpochapụ ya, kpochaa ya na ngwaahịa corrosion ma mịrị amị, wee mechie mmanụ ọzọ;
5. Mgbe a na-echekwa magnesium alloy ruo ogologo oge, a ga-enyocha ya mgbe niile na a ghaghị ime ọgwụgwọ mgbochi corrosion dị mkpa.
