Определены технологические режимы, ответственные за получение аморфизированных покрытий, на
базе теоретического анализа условий структурообразования покрытий, системы Zr-Al-B. Получен наиболее
предпочтительный вариант максимально износостойкого покрытия, структура которого представлена
аморфной матрицей с незначительными микрокристаллическими включениями твёрдых фаз.
Presented by the study of the influence of main technological parameters on the physical, mechanical and tribological properties of the coatings Zr-Al-B in a variety of test conditions. On the basis of theoretical analysis of the conditions of structure surfaces of Zr-Al-B defined process conditions responsible for obtaining amorphous coatings. By changing the ratio of fuel gas and oxidant in the detonation mixture of neutral gas additives, the particle size of the sprayed powder, rate and length of the barrel unable to resuscitate ratio between amorphous and crystalline components in the coating. To cover the system Zr-Al-B justified amount of amorphous component at around 70 ... 80 %. Modes of detonation spraying to ensure minimization of dissolved gases in the coating , the corresponding increase in the amount of amorphous phases are , with the maximum strength of the adhesion of the coating corresponds to regimes under which ensures a maximal - its content. Defined process conditions responsible for obtaining amorphous coatings on the basis of theoretical analysis of the conditions of structure coating system Zr-Al-B. In the results of the study of wear resistance of amorphous coatings found that the most preferred embodiment of the coating in terms of maximum wear resistance are covering, the structure of which is represented by an amorphous matrix with minor inclusions of microcrystalline solid phases.
