Hafnium carbide coating has high hardness, excellent wear resistance, good resistance to corrosion, and low thermal conductivity, which are ideal characteristics for use in high-temperature applications.
In this article, a series of hafnium carbide coatings with different carbon contents were synthesized by reactive magnetron sputtering, and the effects of different [C.
The phase constituting hafnium carbide coatings was determined by X-ray diffraction (XRD) on the Dmax-2550/PC diffractor with Cu-[K.
The composition of hafnium carbide coatings acquired at different [C.

Examples include 20-vol% indium tin oxide in PMMA, 20- to 80-vol% hafnium carbide fillers in PMMA, and 15- and 20-vol% copper in PMMA and PVA.
Such ceramics are difficult to mold into body-friendly shapes, since they are made of very hard ceramics such as boron carbide, zirconium carbide, hafnium carbide, titanium carbide, or zirconium diboride.
