Effect of the Flux-Cored Powder Wire Charge Composition on the Stability of Surfacing

Effect of K2CO3, TiO2, and CaF2 on the stability of surfacing, when these components are introduced into the composition of flux-cored wire charge of the C–Cr–B alloying system intended for the deposition of abrasion-resistant coatings, is studied. Oscillograms of the deposition of the fabricated flux-cored wires are obtained under various conditions ensuring electrode metal transfer with and without short circuits. The oscillograms are used to reveal the effect of the components of flux-cored wires charge on the stability of the process. The effect of the introduced components on the coefficient of burnout and splashing losses and the fraction of participating the base metal are detected under various surfacing conditions.
