| Abstract |
Results of these studies: gas flow rate and composition and the nozzle diameter of the torch have a determining influence on the noise level and spectrum. Reduction of the spraying rate, inversely proportional to the cross-sectional area of the nozzle, markedly reduces the noise level. Other noise control measures: use of plasma torches in which the powder to be sprayed is introduced before reaching the anode; increasing the proportion of argon in the gas mixture; acoustic enclosure of spray-coating booths. |
