A METHOD OF COATING A MEMBER HAVING A NICKEL SURFACE, INCLUDING THE STEPS OF: MIXING THE OXIDES OF LEAD, BISMUTH AND SILICON AND AT LEAST A FIRST ADDITIONAL GLASS MODIFIER IN PERCENTAGES TO PROVIDE A SUBSTANTIALLY GREATER PERCENTAGE BY WEIGHT FOR THE OXIDE OF LEAD THAN FOR THE OXIDES OF ANY OF THE OTHER ELEMENTS IN THE MIXTURE; HEATING THE MIXTURE TO A FIRST TEMPERATURE LESS THAN THE MELTING TEMPERATURE OF NICKEL TO MELT THE OXIDES FOR THE PRODUCTION OF A FIRST FLUX HAVING A MELTING TEMPEATURE CONSIDERABLY LESS THAN THE MELTING TEMPERATURE OF NICKEL, QUENCHING THE FIRST FLUX, AND PRODUCING FINE PARTICLES OF THE FIRST FLUX; MIXING THE OXIDES OF LEAD, BISMUTH AND SILICON AND AT LEAST A SECOND ADDITIONAL GLASS MODIFIER IN PERCENTAGES TO PROVIDE A SUBSTANTIALLY GREATER PERCENTAGE BY WEIGHT FOR THE OXIDE OF LEAD THAN FOR THE OXIDES OF ANY OF THE OTHER ELEMENTS IN THE MIXTURE, HEATING THE MIXTURE TO A SECOND TEMPERATURE LESS THAN THE MELTING TEMPERATURE OF NICKEL BUT GREATER THAN THE TEMPERATURE OF HEATING THE FIRST MIXTURE TO MELT THE OXIDES FOR THE PRODUCTION OF A SECOND FLUX HAVING A MELTING TEMPERATURES GREATER THAN THAT OF THE FIRST FLUX BUT CONSIDERABLY LESS THAN THE MELTING TEMPERATURE OF NICKEL, QUENCHING THE SECOND FLUX, AND PRODUCING FINE PARTICLES OF THE SECOND FLUX; PROVIDING PARTICLES OF A REFRACTORY MATERIAL; INTIMATELY MIXING THE PARTICLES OF THE REFRACTORY MATERIAL AND THE FIRST AND SECOND FLUXES TO PRODUCE A RESULTANT MATERIAL; AND APPLYING THE RESULTANT MATERIAL TO THE NICKEL SURFACE OF AT TEMPERATURE LESS THAN THE MELTING TEMPERATURE OF THE NICKEL BUT GREATER THAN THE MELTING TEMPERATURES OF THE FIRST AND SECOND FLUXES.
