The paper examines how the porosity of electrode materials used to restore parts influences the electrospark deposition process. A higher porosity decreases the heat conductivity of the electrode material. A smaller amount of heat spreads along the e

The hardness, wear resistance, and internal stresses of spark-deposited iron-based coatings are determined. The slower deposition at greater spark discharge energy and the formation of plastic austenite promote the relaxation of internal stresses in

The composition of iron-based electrode material for the spark restoration of steel parts is optimized. The material permits depositing coatings twice as thick as those made of sormite. Varying the content of chromium carbide, one can change coating

A study has been made on how heat treatment affects internal stresses in hard-alloy spark coatings on steel 45. Annealing the hardened steel before coating reduces the depth to which tensile stresses penetrate, while annealing after coating reduces t

Bovine leukocyte adhesion (BLAD) is a recessive autosomal disease in Holstein-Friesian cattle caused by point mutation in CD18 gene encoding neutrophil-surface glycoprotein. To determine BLAD carriers, the convenient primers were chosen to amplify th
