Cad iad Cóimhiotail Gailliam-Bhunaithe

Tá cóimhiotail Gailiam-bhunaithe bunaithe ar ghailliam, ag cur miotail eile, mar shampla tungstain, cóbalt, tíotáiniam, iarann ​​agus miotail eile, chun cóimhiotail ghailliam-bhunaithe a dhéanamh.

Is cóimhiotal nicil-bhunaithe é Ni65WC, agus tá cruach dhosmálta nicil-bhunaithe ann freisin, mar shampla 304, 316 agus steels dhosmálta eile. De ghnáth tá cruas ard, friotaíocht caitheamh maith, agus friotaíocht maith teocht ard ag cóimhiotail nicil-bhunaithe a chuirtear le tungstain, moluibdín, cóbalt, tíotáiniam, etc. Úsáidtear iad de ghnáth chun críocha speisialta, mar chóimhiotail mhianadóireachta, cóimhiotail chaitheamh-resistant, cótaí, cóimhiotail uirlisí, agus maighnéadas láidir.

In addition to bearing abrasive wear, adhesive wear and other types of wear, a class of nickel alloys that also withstand medium corrosion and high temperature oxidation. Therefore, the working conditions of nickel-based are much more complicated than those of general wear-resistant steel and wear-resistant cast iron. The chemical composition of wear-resistant gallium-based alloy is (%): C 0.10～0.20, Mn 0.25, Si 0.60, Cr 14.00～17.00, Mo 4.50～6.00, Al 2.5～3.50, Fe 8.00～12.00, Ti 1.50～2.50, Ni margin. The tensile strength at 820°C was 520 MPa and the elongation was 3%. This material is generally used as wear-resistant parts that work in air or low-lubricating liquids, such as valves, pump parts, pistons, piston rings, seals, brakes, thrusters in petrochemical equipment, atomic energy equipment, and jet aircraft and internal combustion engines. Rods, vanes and blades, etc.
