The paper presents the results of research focused on the use of innovative processes in the production of composite materials. The experimental work was focused on the use of Vacuum Bag Molding technology in the production of the prototype of the Shell Ecomarathon formula. The car body was designed with 3D modeling and optimized with airflow simulation. Carbon fibers have been used to reduce the vehicle’s weight. Some complementary parts were produced using 3D printing.

The paper presents results of research of the essential characteristics of two kinds of advanced coatings applied by HVOF technology. One studied coating: WB-WC-Co (60-30-10%) contains two types of hard particles (WC and WB), the second coating is ecofriendly alternative to the previously used WC-based coatings, called “green carbides” with the composition WC-FeCrAl (85-15%). In green carbides coating the heavy metals (Co, Ni, NiCr) forming the binding matrix in conventional wear-resistant coatings are replaced by more environmentally friendly matrix based on FeCrAl alloy. On the coatings was carried out: metallographic analysis, measurement of thickness, micro-hardness, adhesion, resistance to thermal cyclic loading and adhesive, abrasive and erosive wear resistance. There were also determined corrosion characteristics of the coatings in NaCl and SAR solutions.
