| Abstract: | In this paper, two technical methods: the diamond coating and the addition of rare earth elements to matrix materials, are proposed, in line with the results derived from the experimental research, to improve the thermal stability of diamonds, the cohesion of matrix materials to the diamonds and their corresponding performance. These two technical methods can serve as favorable conditions for the substitution of Fe for Co in the matrix material. |

| Keywords: | diamond coating addition of rare_earth elements substitution of Fe for Co |
