Abstract
A method for sinter coating a work-piece is disclosed, the work-piece having at least two sections of different surface-related heat capacities. The method includes a first step of pre-heating the work-piece to a first temperature that is higher than a fusion temperature of a sinter coating material. The method also includes a step of rapidly heating of the work-piece to a second temperature that is higher than the first temperature. However, the rapid heating step is halted before the temperature of the work-piece section with the greater surface-related heat capacity matches the second temperature. The work-piece then has a subsequent step of application of the sinter material to the work-piece. The step of shock heating of the work-piece is preceded by a step of pre-heating the work-piece under conditions which, with continuing effect on the work-piece, bring the work-piece under conditions which, with continuing effect on the work-piece, bring the work-piece to a second temperature between the fusion temperature of the sinter material and the first temperature.
