项目摘要

We have devised a production method that creates metal inlays without a casting process.2003We understood that silver clay made inlay by sintering for four minutes in a microwave oven.After soaking surface gold alloys (pressure welded sheets of 50 microns and 100 microns) in 0.1% solution of sodium sulfide at 37℃ for 3 days, their L^* are 71.5 and 73.5 respectively, and they meet specifications (T6105)2004We obtained Compressive strength 169 MPa by sintering powder of silver (0.7g), powder of copper (0.15g) and powder of iron (0.15g) for four minutes in a microwave oven.2005 Improvement of sintering shrinkagePowder of silver was exposed to the temperature that several hundred degrees are high in than a silver melting point.Then, I thought that I could improve the shrinkage because only the surface fired.When powder of silver and porcelain fired, changed color in yellow.Twice firing was able to improve 2.5% sintering shrinkageUtilizing a microwave oven and a laser system, metal inlays can be made in thirty minutes.

我们发明了一种无需铸造就能制造金属镶嵌物的生产方法。2003我们了解到，银粘土通过在微波炉中烧结4分钟制成镶嵌物。（50微米和100微米的压焊板）在0.1%的硫化钠溶液中于37℃下放置3天，它们的L^* 分别为71.5和73.5，通过对银粉末的烧结，获得了169 MPa的抗压强度（0.7克），铜粉（0.15克）和铁粉（0.15克）在微波炉中加热四分钟。2005烧结收缩的改善银粉末暴露在比银熔化高几百度的温度下点。然后，我认为我可以改善收缩，因为只有表面烧制。当银和瓷粉烧制时，颜色变成黄色。两次烧制能够提高2.5%的烧结收缩率利用微波炉和激光系统，可以在30分钟内制作金属嵌体。
