摘要

An erosion-resistant lacquer-type coating is produced by coating a substrate with a dispersion of a binder solution, contg. by wt.% 10-20 CrO3; 20-30 H3PO4; 20-70 H3PO3; 0-5 AlPO4; balance H2O with a good electrically conducting metal powder from Al, Ag, Au, Cu, Ti, Pd, Sn or alloys of these. The pref. metal powder is Al or Ti powder added in an equal wt. proportion to the binder. H3PO3 and H3PO4 are added in approx. equal amounts with CrO3 present in amount 0-10 wt.% (sic) and AlPO4 in amount 0-2.5 wt.%. The solution of binder is applied to the substrate by dipping, painting, brushing on, pressing on etc. followed by firing at below 200 deg.C using a micro wave or similar electromagnetic or high energy beam. The coating is then compacted in a mould whose inner wall is coated with the metal powder to carry out a pack-cementation process.
