    Title: ALLOYING AND POST-HEAT-TREATMENT OF THERMAL-SPRAYED COATINGS OF SELF-FLUXING ALLOYS

    Relation: SURFACE & COATINGS TECHNOLOGY,Volume: 58,Issue: 1,Pages: 73-77,Published: JUN 18 1993
    Keywords: thermal-sprayed self-fluxing
    hardness
    wear resistance
    Abstract: The hardness and wear resistance of a thermal-sprayed self-fluxing alloy (Ni-17wt.%Cr-3.3wt.%B-4.3wt.%Si-4.2wt.%Fe-0.9wt.%C) is improved by adding 20 wt.% of B13C2 to the powder and heating the coating at 1030-degrees-C in a vacuum of 10(-2) Torr. Porosity is decreased from 20 to 0.3 vol.% by the heating if a pre-heating at 950-degrees-C is carried out to facilitate the escape of trapped gases. The presence of numerous precipitates of Cr3C2, and CrB in the coating is consistent with a Rockwell hardness of HRC 63. The abrasive wear resistance is much improved compared with that of Stellite 6B.
