Kubatanidza plasma kwe cobalt-based alloys kugadzira weld overlays dzemhando dzakasiyana dzehukukutu

Ma alloys akavakirwa paCobalt imhando dze alloys dzine resistance ye oxidation yekupisa kwakanyanya kusvika kumadigirii 1000 Celsius. Dzinoratidzawo resistance yakanaka kuneta kwekupisa kwakanyanya uye ngura inopisa, zvichiita kuti dzishandiswe zvakanyanya pakugadzirisa nekudzivirira mavharuvhu, zvigaro zvevharuvhu, mabheyaringi, nezvimwe zvinhu zvekushanda, pamwe nekugadzira pamusoro pemapaneru akasiyana-siyana anodzivirira kupera uye maroller. Kuwedzera pakudzivirira kwavo oxidation yekupisa kwakanyanya, ma alloys akavakirwa pacobalt anoratidzawo resistance yakanaka ye ngura ku50% phosphoric acid uye 5% sulfuric acid. Zvichienderana nekuoma kwe cobalt-based alloy powder, mashandisirwo akasiyana anogoneka. Parizvino, fekitori yedu inogadzira cobalt-based alloy powders ane mazinga ekuoma anotevera:

DG.Co6:

HRC: 37-43,

Kuumbwa kwemakemikari: C1.2, Cr20.3, Fe2.5, Ni2.5, Si1.1, W4, Co Bal.

Mashandisirwo akajairika: mashizha eturbine, mavharuvhu einjini, mavharuvhu anodziya zvakanyanya uye ane kumanikidzwa kwakanyanya, nezvimwewo.

DG.Co12:

HRC: 40-50,

Kuumbwa kwemakemikari: C1.5, Cr30.5, Fe2.5, Ni2.5, Si1.5, W8, Co Bal.

Mashandisirwo akajairika: mavharuvhu anodziya zvakanyanya uye anomanikidza zvakanyanya, mazino ekucheka, screws, nezvimwewo.

DG.Co190:

HRC: ≥57,

Kuumbwa kwemakemikari: C3.3, Cr26, Si0.8, W14, Co Bal.

Mashandisirwo akajairika: Zvishandiso zvakasiyana-siyana zvekuboorera zvinoshandiswa muindasitiri yepeturu.

DG.Co21:

HRC: 25-30,

Kuumbwa kwemakemikari: C.025, Cr27.5, Fe2.0, Ni2.5, Si2, W0.15, Mo5.5, Mn1.0, Co Bal.

Mashandisirwo akajairika: mashizha eturbine, mavharuvhu akasiyana-siyana, zvigaro zvevharuvhu, nezvimwewo.

DG.Co158:

HRC: 38-42,

Kuumbwa kwemakemikari: C0.75, Cr26.0, Fe3.0, Ni3.0, Si1.9, B0.7, W5.5, Mo0.5, Mn0.1, Co Bal.

Mashandisirwo akajairika: zvikamu zvisingapfeki zvenzvimbo dzekushanda dzinopisa zvakanyanya, zvinodzivirira ngura negasi rinopisa uye kuputika.

DG.Co158V:

HRC: 45-50,

Kuumbwa kwemakemikari: C1.0, Cr30.0, Fe4.0, Ni3.0, Si1.0, B0.7, W8.0, Mo0.5, Mn0.1, Co Bal.

Mashandisirwo akajairika: zvikamu zvisingapfeki zvenzvimbo dzekushanda dzinopisa zvakanyanya, zvinodzivirira ngura negasi rinopisa uye kuputika.

Mazhinji emhando dze cobalt-based alloys anogadziriswa ne plasma welding, uye mashoma anogona kugadziriswa ne oxyacetylene spray welding. Parizvino, mhando dzedu dze cobalt-based alloys dzinogadzirwa ne gas atomization. Kana tichienzanisa ne upfu hunogadzirwa ne water atomization, upfu hunogadzirwa ne gas atomization hune mativi akatenderera uye mwero wekuyerera uri nani.
