Abstract
A tire stud according to the present invention is manufactured from ceramic, and thus has characteristics of causing the strength of ceramics to recover through crack healing while lowering residual stress by improving a sintering process. In addition, abrasion resistance is improved by further adding a sintering aid and an organic oxide during sintering, and thus friction with a road surface can always be maintained to be constant and life span can be greatly increased.
Claims5
A tire stud comprising:
- a main body;
- a support positioned at a lower end of the main body;
- and
- a fastening portion that is positioned at an upper end of the main body and is formed to have one surface sunken toward a center of the main body by a certain degree or more,
- wherein the main body, the support, and the fastening portion are manufactured by putting one or two or more ceramics selected from the group consisting of silicon oxide, silicon carbide, silicon nitride, silicon alumina nitride, aluminum oxide, zirconium oxide, and cordierite in a mold and sintering.
