摘要

本研究目的是將鎳基合金粉末噴焊系統之技術應用於耕耘刀上，配合所研製合金粉末噴焊機構進行耕耘刀表面硬化處理，並利用紅外線熱像測溫儀擷取瞬間熱影像與熱輻射溫度，來檢測耕耘刀鍍層的表面溫度。試驗結果顯示：在相同測溫點，熱像儀所擷取噴焊瞬間熱影像及經八秒表面散發出之溫度值均與國外學者所研究之結論相符合；同時當測試兩片耕耘刀時，兩組熱輻射影像相對應點溫度約略相同且皆呈現均勻分佈。因此，本研究證實使用所研發之合金粉末噴焊機構鍍層時確能達到耕耘刀噴焊鍍層表面溫度的均勻性、精密性與穩定性。

The purpose of this study is to apply the Nickel-Base alloy powder welding technique to the blades of tillers. In order to measure surface temperature of coated blade, this research tried to use designed alloy powder spray-welding mechanism to precede the surface hardening for the blades, and to use the infrared thermal imager to collect the instant heat image and its radiant temperature. Experimental results showed that, at the measure spots, both the instant heat image displayed in the thermal imager and the surface temperature of the heat radiation collected after eight seconds consistent with the conclusions addressed by other foreign researchers. At the same time, two sets of heat radiant temperatures obtained from the thermal imager were uniformly distributed over two pieces of tiller blades. Therefore, it can be proved that the coating surface of the tiller blades treated with alloy powder welding would have more uniform, precise and stability when using the alloy powder spray-welding mechanism de veloped in this study.
