Abstract

The present invention relates to powder metallurgical technology, and is especially titanium monoxide-base cermet material and its preparation process. The present invention features that into the Fe-Cr alloy on titanium monoxide base with oxygen index of 0.8-1.2, one or several of Mo, Si and Ni elements in 0.1-20 5 are added. The titanium monoxide-base cermet gold-imitating material has chroma difference to 24K gold of 0.005-0.010, stable color in atmosphere, no color change after setting in gold corroding liquid at 25 deg.c for over 40 days, bending strength of 440-800 MPa, breaking toughness of 5.2-10.0 MNm-3 / 2. The titanium monoxide-base cermet gold-imitating material has excellent comprehensive performance.

Description

Technical field:

[0001] The invention relates to the field of powder metallurgy, in particular to a titanium monoxide-based cermet imitation gold material and a preparation method thereof. Background technique:

[0002] At present, the imitation gold alloy materials that have been applied or are being studied at home and abroad include: copper-based alloy imitation gold material, low-K gold imitation gold material, TaC-based cermet gold-imitation material and TiN-based cermet gold-imitation material.

[0003] Copper-based alloy imitation gold materials have been widely used, but the problems of poor corrosion resistance and discoloration resistance in sweat and atmosphere have not been fundamentally solved, and the hardness is low and easy to be scratched;

[0004] Low-K gold imitation gold materials are generally Cu-Au alloys with a gold content of less than 9%, and the price is still relatively expensive, and its color and tarnish resistance are far inferior to pure gold; ...
