The paper presents results of the research carried out by the authors in different fields of plasma surface technologies applications. Three groups of different surface engineering technologies are shown in the paper. The first one concerns the possibility of using the duplex treatment technology for creation of biocompatible diamond-like a-C:H films. The paper presents research results concerning influence of the process parameters of the a-C:H coatings creation by means of the RF PACVD method in the pure methane atmosphere on their phase structure and mechanical properties. In the second case authors present the concept of a new special multilayer thermal barrier coatings with the PAPVD diffusion barrier layers based on aluminium oxide. As the last one the special application of plasma techniques for creation of composite materials characterized by the muffling of mechanical vibration was presented.
