An aqueous washing system and method for washing articles such as engineering components, comprising placing the articles into a process chamber 10 and supplying from a supply tank 11 an aqueous washing fluid at a temperature at or above 100 {C. A head of pressure is established above the fluid in tank whereby the fluid may be transferred by a pump P1 to the process chamber. After a washing cycle the articles are rinsed by clean water and then vacuum dried before removal from the process chamber. The head of pressure over the fluid in the supply tank can be created by the heated and expanded air from the process chamber, or from a stored supply of compressed air. Means are supplied to rotate and agitate the components and to automate the process. The washing fluid may contain surfactants, corrosion inhibitors, tension reducers and/or metal passivators and may be filtered during use. The system may be used for hot curing of resin impregnated porous metal components. |
