Abstract

See full text

An effervescent suspension for metallic quenching and coating purposes, is implemented by providing and an effervescent tablet with mixture comprising a solid alkaline, a solid acid, and noble metal particles. The mixture is added to water to produce a reaction in the water resulting in the release of CO2 gas, which disperses the noble metal particles in the water to provide a suspension. A hot metal material, having a temperature below its melting point, is immersed in the suspension to provide a quenched metal that has a temperature below its melting point in the suspension to provide a quenched metal coated with noble metal particles. The solid alkaline may comprises sodium bicarbonate (NaHCO2) powder and sodium carbonate (Na2CO3) powder. The solid acid may comprise monosodium phosphate (NaH2PO4) powder.
