WebThe silicon nitride coatings were deposited from a mixture of SIC14 and N H 3 in argon by the r.f. plasma technique onto stainless martensitic steel (AISI type 410). N H 3 is preferred to N2 as a nitriding agent because of the high dissociation energy of N2 11. SiC14 is preferred to silane as the silicon source for its easier and safer handling.
