Abstract

Metal articles are coated by applying to the surface thereof a slip mixture including aluminium or an aluminium alloy in the form of small particles suspended in a water vehicle with an inorganic inhibitor for preventing reaction between said coating metal particles and the water, said inhibitor consisting of a fritted ground alkaline earth borate, or alkali-alkaline earth borate, and firing the coated article at a temperature which will cause the coating metal to develop a diffused protective coating layer on the surface of the article. "Fritted" is defined as "smelted and cooled". The inhibitor may also include aluminium fluoride and/or silicon oxide and may be prepared by fusing together (1) barium oxide (or carbonate) boron oxide (or boric acid) and aluminium fluoride, or (2) sodium oxide (or carbonate) barium oxide (or carbonate) boron oxide (or boric acid) and silicon oxide (silica). When the alternative compounds are used instead of the oxides, water and carbon dioxide are evolved. The inhibitor may be ground to pass a 200 (U.S.) mesh sieve and the coating slip may contain 32-93.5 parts of aluminium or alloy, 0.5-5.0 parts of inhibitor, 6-30 parts of clay and 0-60 parts of alumina or zirconia by weight. The coating may be applied by slushing, brushing, dipping or spraying to surfaces of mild steel or stainless steel, and fired at 1600 DEG to 1900 DEG F. Specification 868,933 and U.S.A. Specifications 1,655,269 and 1,817,888 are referred to.
