Abstract (en)

[origin: WO0105546A1] A downhole tool or other product (P) made essentially of aluminium base material is provided with a hard-faced surface comprised by geometric elements or rough particles (2a) of hard material. Filler material (3) serving to secure the elements/particles to the surface is applied by gas-shielded metal arc welding (e.g. TIG welding) in pulsed mode, so as to fill in the spaces between the elements/particles. In this way, substantial hard-facing can be applied to aluminium articles, where conventional hitherto only steel articles have been susceptible to substantial hard-facing.
