1. Introduction to Self-Fluxing Alloy Powders
Self-fluxing alloy powders are a class of metal powders engineered to promote metallurgical bonding and surface integrity during thermal spraying processes, such as flame spraying and plasma spraying. These powders are widely used in wear-resistant and corrosion-resistant coatings thanks to their ability to form a dense, adherent layer without the need for external fluxing agents.
Self-fluxing powders typically include elements such as:
- ニッケル（Ni）
- クロム（Cr）
- ホウ素（B）
- ケイ素 (Si)
- 鉄（Fe）
These powders are prealloyed and engineered to melt and flow easily during spray deposition, offering excellent bonding and mechanical properties.
