| Popis: | The internal diameter (ID) coating by means of thermal spraying is currently experiencing growing interest in science and industry. In contrast to the well-established plasma- and arc-based spray techniques, there is a lack of knowledge concerning kinetic processes such as HVOF, HVAF and warm spray (WS). A major challenge represents the necessity of short spray distances and the compact design of novel ID spray guns with reduced combustion power. Conventional WC-Co powders (��� 45 + 15 ��m) are not able to achieve a sufficient heat and momentum transfer. The use of fine powders Journal of thermal spray technology;30. 2021, pp 1344���1364 |
