  • Copolyamide powder as a pore former in regenerable ceramic particulate filters
    Patent number: 8449641
    Abstract: 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 >350 m2/l.

  • Method for sinter coating
    Patent number: 7790224
    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.
