鎳基合金和碳化鎢（WC）的複合材料已被廣泛應用於各種領域中，由於鎳合金的高耐腐蝕性和碳化鎢的高耐磨損性。真空燒結是有效製造硬質合金的方法，可以防止材料氧化和脫碳現象。在這項研究中，在不同的成分比例Ni60合金（Ni/Cr/B/Si）和WC組成的複合材料(30.0 - 39.4 vol% WC)以不同的燒結燒結溫度（1125℃、1150℃、1175℃、1200℃）進行。優化結果顯示，碳化鎢複合材料30.0 vol％WC在1175℃，硬度達 HV889 kgf / mm2和較低的腐蝕速率7.26 mg / cm2 / hr，測試用70 % 硫酸。根據XRD、SEM和EDS微觀結構的分析顯示，燒結溫度的升高至1200℃，產生W2C及 Ni2W4C造成 Ni60-WC複合材料硬度及耐腐蝕性的下降。

Composites based on nickel alloys and tungsten carbide (WC) have been widely used in various fields, due to high corrosion resistance of nickel alloys and the high wear resistance of tungsten carbide. Vacuum sintering process is an effective method for producing cemented carbides as the vacuum environment can prevent the materials from being oxidized and decarburized. In this study, composite materials composed of Ni60 (Ni/Cr/B/Si) and WC at various composition ratios (30.0 To 39.4 vol% WC) were sintered at different sintering temperatures (1125°C, 1150°C, 1175°C and 1200°C). Optimized results indicated that the composite with 30.0 vol% WC in the composite sintered at 1175 o C, a hardness as high as Hv 889 kgf / mm2 and a corrosion rate as low as 7.26 mg / cm2 / hr, tested using 70% sulfuric acid, can be achieved. The microstructural analysis based on XRD, SEM, and EDS indicated that Sintering temperature to 1200℃, will produce W2C and Ni2W4C, resulting in a decline Ni60-WC composite hardness and corrosion resistance.
