    • PROBLEM TO BE SOLVED: To provide an apparatus (10, 50) for manufacturing a deposited film (12, 86), and to provide a deposition method thereof and an article (80).SOLUTION: The apparatus (10) includes: a thermal spray gun (16) including a combustion chamber (22); a combustion zone (28); an air injection port (18); a fuel injection port (20); a nozzle (30); and a liquid injection port (34). The combustion zone (28) is positioned between the inlet side (24) and outlet side (26) of the combustion chamber (22). The method includes, among other things, the steps of: providing a fuel and an oxidizer inside the combustion zone (28); initiating combustion inside the combustion zone (28); and directing products of the combustion toward the outlet side (26) to create a combustion product stream. The method also includes the steps of: introducing a feedstock mixture including a feedstock material and a liquid into the combustion product stream to create an entrained feedstock stream; and expelling the entrained feedstock stream from the spray gun through the nozzle to form the deposited film on a surface of the article.
    • 要解决的问题:提供一种用于制造沉积膜(12,86)的设备(10,50),并提供其沉积方法和制品(80)。 解决方案:装置(10)包括:包括燃烧室(22)的热喷枪(16); 燃烧区(28); 空气喷射口(18); 燃料喷射口(20); 喷嘴(30); 和液体注入口(34)。 燃烧区(28)位于燃烧室(22)的入口侧(24)和出口侧(26)之间。 该方法尤其包括以下步骤:在燃烧区(28)内提供燃料和氧化剂; 在燃烧区(28)内引发燃烧; 以及将燃烧产物引向出口侧(26)以产生燃烧产物流。 该方法还包括以下步骤:将包括原料和液体的原料混合物引入燃烧产物流中以产生夹带的原料流; 并且将来自喷枪的夹带的原料流通过喷嘴排出,以在制品的表面上形成沉积膜。 版权所有(C)2012,JPO&INPIT
