In order to compare with characteristics of the plasma jet described in the previous report, some properties of the oxy-acetylene flame for spraying which is now utilized extensively, that is, the gas velocity, the temperature distribution, the composition of gas and the mixing rate of air into the flame and the flying velocity of spraying particles (Mo, Al_2O_3 and ZrO_2) along the flame axis at the various distances from the nozzle under the ordinary operating conditions, are experimented. For instance, at the 100'mm distance from the nozzle, the summary of results is the following. (1) Flying velocity of spraying particle Powder process Al_2O_3 : 55m/sec, ZrO_2 : 40∿45m/sec Wire process Mo : 60m/sec (2) Gas velocity Powder process 50m/sec, Wire process 160m/sec (3) Temperature Powder process 1,900℃, Wire process 500℃ (4) Mixing rate of air into flame Powder process 60%, Wire process 85%
