Plasma-sprayed iron-base wear-resistant coatings containing titanium diboride
  • Description:
    "Cobalt-base hardfacing alloys used for wear resistance consist almost entirely of metals largely imported into the United States. As part of an overall research program to help alleviate this foreign dependency, the Bureau of Mines has been investigating an iron-base alloy system as a potential replacement for cobalt-base alloys for some uses. To ascertain the melting ranges, thermal analyses were made of cast heats of alloys containing, in weight percent, 59-61 fe, 16-19 cr, 8-9 ni, 1 mn, 1 w, 1 mo, 0.5 Cb, 0.6 Si, 0.3 C, and 0-12 stoichiometric tib2. Powder alloys within this range of composition, prepared by mechanical alloying, were sized and applied to mild steel test coupons by nontransferred-arc plasma spraying. The resulting thin coatings were >95 pct dense, with bond strengths of 35 mpa and hardness of 400 to 840 diamond pyramid hardness. Abrasive and adhesive wear test data were compared to those of a plasma-sprayed cobalt-base alloy. A range of boride contents resulting in most promising properties was determined for further research." - NIOSHTIC-2 NIOSHTIC no. 10004767
