Реферат: At present, boron carbide, B4C, coatings are in high demand as protective plasma-facing first-wall materials in thermonuclear reactors. In the present work, for the first time, binderless B4C coatings were obtained by detonation spraying (DS). The coatings were deposited on a tungsten sublayer deposited on a steel substrate. DS was performed using an acetylene-oxygen explosive mixture of C2H2 + 1.1O2 composition. This enabled efficient heating of the boron carbide particles during spraying. The X-ray phase analysis confirmed that the B4C phase was the major phase of the coatings. The coatings had a porosity of 1.4 ± 0.2 %, a hardness of 13.9 ± 1.6 GPa, and a cohesion of 12.4 ± 0.6 MPa. Based on results of the present work, the DS technology can be recommended for depositing protective plasma-facing binderless B4C coatings on the first wall of a thermonuclear reactor.
