A process for producing a regenerable ceramic particulate filter for diesel vehicles is described, wherein a material comprising silicon-containing particles is pyrolyzed in the presence of a polyamide. The resulting particulate filters have a BET surface area of &#x3e;350 m/l.

Copolyamide powder as a pore former in regenerable ceramic particulate filters

Reactive hotmelt adhesives based on copolyamide can be used in hybrid components. These hybrid components find application in, for example, vehicle construction and aircraft construction.

Hybrid components containing reactive hotmelt adhesives

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.
