The cobalt base laser cladding layers were investigated after two years of service in two laboratory diesel engines. The microstructures of the clads after service did not demonstrated serious degradation process. Chemical compositions of the used layers and changes in hardness were described. These sorts of layers are suitable for long time service with out substantial damages.
