“…Coatings 2019, 9, x FOR PEER REVIEW 2 of 12 coating described in this article has been made using the friction method, which allows the creation of a joint between the ceramic substrate and the metallization coating, where during the joining process, both materials remain in a solid state. Currently, there is an interest in various types of surface modification processes and bonding with a mechanical method of energy supply; [18][19][20] investigated this approach and found that it makes bonding easier, even for extremely different materials. In the case described in this article, the maintenance of the metal of the resulting coating in the solid state (characterized by high plasticity) results from the supply of energy to the bonding area on the mechanical way (by friction).…”

The article presents selected properties of a titanium metallization coating deposited on aluminum nitride (AlN) ceramics surface by means of the friction surfacing method. Its mechanism is based on the formation of a joint between the surface of an AlN ceramics substrate and a thin Ti coating, involving a kinetic energy of friction, which is directly converted into heat and delivered in a precisely defined quantity to the resulting joint. The largest effects on the final properties of the obtained coating include the high affinity of titanium for oxygen and nitrogen and a relatively high temperature for the deposition process. The titanium metallization coating was characterized in terms of surface stereometric structure, thickness, surface morphology, metallographic microstructural properties, and phase structure. The titanium coating has a thickness ranging from 3 to 7 μm. The phase structure of the coating surface (XPS investigated) is dominated by TiNxOy with the presence of TiOx, TiN, metallic Ti, and AlN. The phase structure deeper below the surface (XRD investigated) is dominated by metallic Ti with additional AlN particles originating from the ceramic substrate due to friction by titanium tools.

Welding is one of the most popular methods of joining elements not only from metal materials, but plastics also. Their great diversity, chemical structure and physical condition in which they are at the temperature of use has a significant impact on the quality of the joints made. Welding is a particularly useful method of joining, for example, during the welding of packaging, where biodegradable plastics that dominate in this technology, for example with aluminum foil, dominate. This article reviews the methods of welding plastics including biodegradable materials.

“…Plastics in the form of granules, powders, flakes, or chips are used as the starting material. Due to the technological process itself, the plasticizing mechanism and its rheological properties, various screw designs as well as boring heads are used, in which appropriate changes in geometry are introduced [13][14][15][16][17][18][19][20].…”

This study presents the extrusion process while using a single-screw extruder and polylactide (PLA). This material belongs to the so-called biodegradable plastics, and is characterized by a higher density compared to typical polymeric materials used to manufacture products in this technology. Various polyethylenes and polypropylenes and their derivatives are commonly used. An evaluation of the extrusion process was carried out for various extruder operating parameters. The rotational speed of the screw and the process temperature were changed. For each rotational speed of the screw, the following readings were made: changes in temperature, active power, current intensity, pressure, and mass of extruded plastics each time.
