AbstractA cermet composition useful in the form of a thin-film as a strain gage consists of 65%-70% by weight chromium, 18%-32% by weight silicon monoxide, and 3%-12% by weight nickel, deposited by vacuum evaporation. After initial deposition, vacuum annealing is accomplished, or, if a more positive TCR and TSS is required, the annealing can be repeated at a higher temperature.
