探讨了18—8不锈钢在牙科铸造中的应用,得到以下结果: (1)、18—8不锈钢的铸造性能较市售镍铬合金略差;有些镍铬合金铸件在去除包埋料时发生破碎,但18—8不锈钢没有这种现象。(2)、18—8不锈钢铸件的机械性能优良,其抗拉强度和伸长率均较镍铬合金为优。(3)、18—8不锈钢铸件的抗腐蚀性能优良。
The application of 18-8 stainless steel in dental casting was discussed. The following results were obtained: (1) 18-8 stainless steel has slightly inferior casting performance compared with commercially available Ni-Cr alloy; some Ni-Cr alloy castings are broken during the removal of the embedded material , But 18-8 stainless steel does not have this phenomenon. (2), 18-8 stainless steel castings excellent mechanical properties, the tensile strength and elongation are better than nichrome. (3), 18-8 stainless steel castings excellent corrosion resistance.
