  • TIRE STUD AND MANUFACTURING METHOD THEREFOR
    Publication number: 20200262249
    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.
