Abstract

A high velocity arc spray apparatus includes a transferred-arc-plasma torch assembly (10) which forms a transferred-arc column. A metal feedstock (122) is fed into the transferred-arc column at an angle, such that no portion of the metal feedstock (122) is closer to the transferred-arc-plasma torch assembly (10) than the leading edge of the metal feedstock (122) in the feeding direction. A power source (27) is coupled to both the metal feedstock and transferred-arc-plasma torch assembly (10) for creating an electrical potential difference between the metal feedstock (122) and the transferred torch assembly (10).
