| Abstract: |
The HVAF process provides a unique combination of thermal and kinetic energy, which presents a challenge to material manufacturers who have over the past years optimized their material offerings to the demands and characteristics of the HVOF process. The recent development of HVAF ID torches, capable of applying the high quality coatings into dimensions less than 100mm (4 ), has provided a further need to optimize spray materials for the best possible interaction between the spray device and the feedstock in order to meet developing coating specifications from various industries.
This paper discusses the methodologies utilized from the points of view of torch design, material manufacture, spray parameter and process optimization, as a means of producing the highest performing coatings to meet specific industry requirements.
