Akpachara anya asatọ maka ịgbado igwe anaghị agba nchara

1. Igwe anaghị agba nchara Chromium nwere ụfọdụ nguzogide corrosion (acid oxidizing, organic acids, cavitation), nguzogide okpomọkụ, na iyi nguzogide. A na-ejikarị ya eme ihe dị ka ụlọ ọrụ ọkụ, kemịkalụ, na mmanụ ala. Chromium igwe anaghị agba nchara nwere adịghị mma weldability, na e kwesịrị ịkwụ ụgwọ nlebara anya na ịgbado ọkụ usoro, okpomọkụ ọgwụgwọ ọnọdụ, wdg.

2. Chromium 13 igwe anaghị agba nchara nwere akwa weld hardening na ọ na-adịkarị mfe mgbawa. Ọ bụrụ na a na-eji otu ụdị chromium igwe anaghị agba nchara (G202, G207) maka ịgbado ọkụ, preheating na 300 ℃ ma ọ bụ n'elu na ngwa ngwa jụrụ ọgwụgwọ na gburugburu 700 ℃ mgbe ịgbado ọkụ ga-rụrụ. Ọ bụrụ na akụkụ ahụ welded enweghị ike ịnweta ọgwụgwọ okpomọkụ mgbe weld weld, mkpanaka chromium nickel igwe anaghị agba nchara (A107, A207) kwesịrị iji.

3. Chromium 17 igwe anaghị agba nchara nwere mma weldability karịa chromium 13 igwe anaghị agba nchara site n'ịgbakwụnye kwesịrị ekwesị stabilization ọcha dị ka Ti, Nb, Mo, wdg iji melite corrosion nguzogide na weldability. Mgbe ị na-eji otu ụdị chromium igwe anaghị agba nchara (G302, G307), preheating na 200 ℃ ma ọ bụ n'elu na tempering ọgwụgwọ na gburugburu 800 ℃ mgbe ịgbado ọkụ kwesịrị rụrụ. Ọ bụrụ na akụkụ welded enweghị ike ịnweta ọgwụgwọ okpomọkụ, chromium nickel igwe anaghị agba nchara (A107, A207) kwesịrị iji.

N'oge ịgbado ọkụ nke chromium nickel igwe anaghị agba nchara, kpo oku ugboro ugboro nwere ike ịkpali carbides, ibelata corrosion iguzogide na n'ibu Njirimara.

5. Chromium nickel igwe anaghị agba nchara mkpanaka nwere ezigbo nguzogide corrosion na nguzogide ọxịdashọn, a na-ejikwa kemịkalụ, fatịlaịza, mmanụ ala, na igwe ọgwụ.

6. Chromium nickel igwe anaghị agba nchara mkpuchi nwere titanium calcium ụdị na obere hydrogen ụdị. Enwere ike iji ụdị calcium nke titanium maka ịgbado ọkụ AC na DC, mana omimi na-agbaze na-emighị emi n'oge ịgbado ọkụ AC na ọ na-enwekarị ọbara ọbara. Ya mere, ekwesịrị iji ọkụ ọkụ DC mee ihe dịka o kwere mee. Enwere ike iji dayameta 4.0 na n'okpuru maka ịgbado ọkụ ọnọdụ niile, ebe enwere ike iji dayameta 5.0 na karịa maka ịgbado ọkụ dị larịị na ịgbado ọkụ fillet.

7. Ekwesịrị idowe mkpanaka ịgbado ọkụ n'oge eji. Ụdị calcium calcium nke titanium kwesịrị akpọnwụ na 150 ℃ maka 1 hour, na obere hydrogen ụdị kwesịrị nkụ na 200-250 ℃ maka 1 hour (adịghị ekwe ka ihicha ugboro ugboro, ma ọ bụghị na mkpuchi na-adịkarị mfe cracking na peeling), iji gbochie mkpuchi. nke eriri ịgbado ọkụ site na ịrapara mmanụ na unyi ndị ọzọ, ka ọ ghara ịbawanye ọdịnaya carbon nke weld ma na-emetụta àgwà nke akụkụ welded.

Iji gbochie inter-granular corrosion nke kpo oku na-akpata, ịgbado ọkụ ugbu a ekwesịghị ịdị elu, ihe dị ka 20% na-erughị nke carbon ígwè ịgbado ọkụ mkpara. Arc ekwesịghị ịdị ogologo, na etiti oyi akwa kwesịrị ịdị jụụ ngwa ngwa. A na-ahọrọ beads weld dị warara.
