In a method for manufacturing a component containing an iron alloy material, a pulverulent pre-alloy is provided. The pre-alloy comprises, in wt. %, 0.01 to 1% C, .0.01 to 30% Mn, &#x2264;6% Al, and 0.05 to 6.0% Si, the remainder being Fe and usual contaminants. The pulverulent pre-alloy is mixed with at least one of elementary Ag powder, elementary Au powder, elementary Pd powder and elementary Pt powder so as to produce a powder mixture containing 0.1 to 20% of at least one of Ag, Au, Pd and Pt. The powder mixture is applied onto a carrier () by means of a powder application device (). Electromagnetic or particle radiation is selectively irradiated onto the powder mixture applied onto the carrier () by means of an Irradiation device () so as to generate a component from the powder mixture by an additive layer construction method.

Method for manufacturing a component containing an iron alloy material

The cleaning performance of washing and cleaning agents, in particular with respect to bleachable stains, was to be intensified without resulting in damage, in the context of use, to the textile treated therewith. This was achieved substantially by employing a bleaching-active species generated electrolytically from an organic mediator compound using a redox reaction.

Washing or cleaning agent with electrochemically activatable mediator compound

The aim of the invention is to improve the cleaning power of washing and cleaning agents, especially with regard to bleachable stains, while avoiding any damage to the textile treated with said washing and cleaning agents. This is substantially achieved by using an electrolytically bleachable species generated by a redox reaction from an anionically substituted 1-hydroxy-2,2,6,6-tetramethylpiperidine, 2,2,6,6-tetramethylpiperidine-N-oxide, or (2,2,6,6-tetramethylpiperidine-1-yl)oxyl.
