  • Method for forming chromium carbide based ceramics composite block gauge
    Patent number: 5637266
    Abstract: A composite ceramic block gauge is formed from a tungsten carbide (WC) reinforced phase and a chromium carbide (Cr.sub.3 C.sub.2) matrix. The finished block gauge possesses excellent properties such as hardness and corrosion resistance and high reflectivity. The block gauges made from Cr.sub.3 C.sub.2 /WC composites can be calibrated using the traditional optical interferometry techniques.
    Type: Grant
    Filed: June 20, 1995
    Date of Patent: June 10, 1997
    Assignee: Industrial Technology Research Institute
    Inventors: Chung-Ping Lai, Cheng-Tsu Fu, Jia-Ruey Duann, Ai-Kang Li, Kai-Li Ko
