У статті проведено аналіз динаміки видобутку, виробництва і цін на промислові алмази і кобальт за
1900-2010 роки. Кобальт, використовується в якості матеріалу основи для алмазного інструменту для різання
натурального каменю та будівельних матеріалів. Інструмент проектування і склад її різання шар грають
ключову роль в економічному обробки матеріалів, де високі вимоги виконані на термін служби інструменту.
Cobalt is characterizining a very special retention of diamond particles. Effective use of diamond grits in diamond impregnated tools strongly depends on interactions taking place at the diamond-matrix interface. The diamonds are held firmly by the matrix when it is characterised by good retentive properties. The retention properties are a complex function of the shape of diamond grits, chemical interactions occurring between the diamond and the metallic matrix, mechanical and thermal properties of the matrix, stress field around the working diamond particles, etc. First of all the diamond particle shape and the mismatch between thermal expansion coefficients of the matrix and diamond should be taken into account for selection of an appropriate matrix. In the new millennium the market for diamond tools continues to grow rapidly. The possibility of substitution of cobalt with the other cheaper alloys was considered which as a matrix material gives similar utilizing properties.
