The invention relates to the field of metallurgy, and more specifically to equipment for testing materials on the shock-abrasive wear, and aims to expand functionality, reducing the size and cost of the test equipment, as well as the simplification of the process of preparation for the test. The technical result is the ability to test materials obtained by powder metallurgy, for shock-abrasive and shock-hydroabrasive wear due to the liquid supply system in the impingement zone and chocking of samples of the particulate metal, and decrease size and cost is achieved by using compression springs.
