For many applications it is necessary to generate wear resistant, hard surface layers. These layers should consist of hard
particles embedded in a ductile matrix. These hard particles are choosen appropriate to the wear conditions and wear
partners like minerals, carbides in an iron base material or coked particles in motor oils. For protective layers it is
important to use low cost hard phase materials, however, some tools require diamonds, the hardest material known. These
have then to be fixed onto the surface. One way of generating such layers is the application of surface treatments with
CO2-lasers. The selection of the hard particles as well as the process control is furthermore dependent on the boundary
conditions like chemical resistivity, desired layer thickness, maximum lagging and price. The generation and deposition
of hard phases is possible by a dispersion of additives into the melt, by forming a hard phase in the pool or by their
precipitation, respectively. In the present paper examples are outlined and some of the current problems are discussed.
