FIELD: applying of coatings. SUBSTANCE: method involves charging powder onto down portion of contact roller positioned in front of sintering zone; conveying powder to sintering zone by means of contact roller. Apparatus has measuring hopper, powder pipeline made from dielectric material; contact roller. Measuring hopper is mounted at a predetermined distance relative to contact roller. Powder pipeline is made expanded in the direction of powder supply and is formed as truncated pyramid. Powder pipeline has output section, which may be regulated. EFFECT: increased efficiency and improved quality of coating. 3 cl
