A1 Fauchais, Pierre T1 Plasma sprayed basalt/chromium oxide coatings JF High Temperature Material Processes: An International Quarterly of High-Technology Plasma Processes JO HTM YR 2007 FD 2007-05-01 VO 11 IS 1 SP 71 OP 81 AB Volcanic basalt and chromium oxide (Cr2O3) have been co-sprayed in air with a direct current (d.c.) plasma to obtain composite coatings. Both powders were simultaneously injected by two separated injectors. The following spray parameters: arc current, hydrogen vol % and total plasma forming gas mass flow rate were optimized as well as injector positions. Different mass ratios of both components were used to achieve coatings. An uniform distribution of basalt among the Cr2O3 lamellae has been observed with SEM for all composite coatings. XRD showed that chromia became amorphous in the composite basalt/chromia coatings. PB Begell House LK https://www.dl.begellhouse.com/journals/57d172397126f956,32f29e6d08d51ac3,256daecb176c213a.html
