摘要

A thermal spray combustion gun (100) including a burner assembly (125), a combustion chamber assembly (130), a middle gun body (110), and a spring (120). The spring (120) is structured and arranged to provide a spring force that maintains a first metal-to-metal seal between the burner assembly (125) and the combustion chamber assembly (130), and maintains a second metal-to-metal seal between the combustion chamber assembly (130) and the middle gun body (110).
