Abstract:
1. A method for sinter coating a work-piece formed from at least two sections having different surface-related heat capacities, comprising: pre-heating the work-piece under conditions which would, if continued, bring the work-piece to a first temperature which is above a fusion temperature of a sinter coating material to be applied to the work-piece; heating the work-piece under conditions which would, if continued, bring the work-piece to a second temperature which is above the first temperature, wherein during the heating step a rate of temperature change of the work-piece is greater than the rate of temperature change which occurs during the pre-heating step; stopping said heating step after the temperature of the section with the greater surface-related heat capacity is above the fusion temperature of the sinter coating material, but before the temperature of the section with the greater surface-related heat capacity matches said second temperature; and applying the sinter coating material to said work-piece after the heating step has been stopped and while the temperature of the section with the greater surface-related heat capacity remains above the fusion temperature of the sinter coating material.
