Abstract
An investigation was carried out about the improvement of steel-ball-detachability from industrial quenching furnace by newly developed plasma weld using ceramics plus alloy powders. The results are as follows.(1) Detachability of steel-ball from furnace wall was very excellent when an overlay was done by plasma welding using NbC plus Ni-Cr-Mo alloy powder.(2) Life of overlayed furnace wall to collapse increased to much longer 120 days from 7 days by NbC plus alloy welding.Keywords
