摘要： The invention is a method of forming a conversion coating on an aluminum surface. According to the method, the aluminum surface is conversion coated by first treating the surface with thermal degreasing or aqueous alkaline degreasing and then contacting the treated surface with an aqueous bath solution of KF. The concentration of KF in the solution is 2.0-25.0 wt. % and the temperature is 90-212° F. for at least 5 seconds. The conversion coating consists essentially of: (a) substantially all K3AlF6 or (b) a mixture comprising a major proportion of K3AlF6 and a minor proportion of KAlF4

摘要： The invention involves a heat exchanger assembly comprising at least one aluminum based tube including magnesium, an aluminum based cladding, and at least one aluminum based component disposed adjacent the cladding. A brazing flux is applied to a joint between the cladding and the component to facilitate brazing in an ambient atmosphere. An aluminum based lithium enriched layer is disposed between the tube and the cladding to scavenge sufficient oxygen from the ambient atmosphere to form an effective barrier against the defusion of magnesium from the tube.

摘要： A brazing furnace includes a housing defining an interior environment having an inlet and an outlet, a plurality of heating elements mounted within the housing and adapted to heat the interior environment to an elevated temperature, and a conveyor belt extending through the housing and supported on a plurality of driven rollers whereby an object placed upon the conveyor belt at the inlet is transported through the inlet into the interior environment and out through the outlet. The conveyor belt includes a plurality of interconnected metal links and a thermal barrier coating applied to the metal links, thereby insulating the metal links and restricting the amount of thermal energy that is absorbed by the conveyor belt as the conveyor belt moves through the interior environment.
