The EU REACH regulations set September 2017 as a “sunset date” for the use of toxic Hexavalent Chromium salts, and as this date is approaching the aerospace manufacturers are looking for alternative coatings to replace Hard Chrome plating (HCP). HCP is widely used in the aircraft industry to protect steel components against wear, corrosion and galling. Hardide-A CVD Tungsten/Tungsten Carbide coating has met the technical performance requirements as a potential alternative to HCP on some specific Airbus aircraft components. This newly-developed CVD coating is crystallized from the gas phase atom-by-atom, forming a uniform layer on both internal and external surfaces and complex shaped parts, which are impossible to coat by thermal spray coatings, considered to be the best available alternative to HCP. Hardide coating consists of Tungsten Carbide nano-particles dispersed in metal Tungsten matrix, combining hardness with toughness and crack-resistance.

Nowadays the treatment of solid surface by powerful streams of charged particles accelerated with power density of ≥106 W/сm2 is widely used for modifications of different materials properties. Fast electron beam power entry into the target material causes intense thermal and deformation processes. The changing of the structure, the phase composition, the microrelief of the treated surface consequently happens. It is often accompanied by the hardening and increase of the wearing properties. Low-energy high-current electron beam usage is proposed as a finishing treatment of product obtained by selective laser melting of heat-resistant nickel alloy EP648. The subject of the research is the surface properties of the product.

FMEA methodology is widely used today for solution of practical analysis problems, quality (reliability, risks) evaluation and assurance etc., owing to a clear and simple algorithm and the absence of restrictions on a subject of analysis (i.e., systems, processes, products). However, the efficiency of applying FMEA methodology for problems solution is determined by the choice of elements of analysis, completeness of identification of potential non-conformities, their causes, frequencies and effects. Quality of manufacture is determined by deviations from requirements of design and manufacturing documentation including drawings. In this article a task of ensuring a steady reduction of deviations from these requirements during manufacture through implementation of preventive actions combined with control of time and costs for correction of non-conformances is considered.

In order to predict the fatigue life of heavy commercial vehicles thrust rod made of rubber material dumbbell specimens and uniaxial tensile fatigue tests. Based on the measured data samples to the maximum principal strain injury parameters established rubber uniaxial fatigue life prediction models. In the longitudinal tension and compression loading, fatigue life V rods were predicted, and by the uniaxial fatigue test verification, the results show that the maximum principal strain prediction model, the maximum error is less than 10% predicted better results. Show by dumbbell specimen data, the establishment of a spherical hinge rubber life prediction model method, it is possible to predict the fatigue life of the thrust rod.

Organic brake pads for automotive can be defined as brake linings where the bonding matrix is constituted of high-temperature thermosetting resins. Bonded together inside the polymeric binder are a mix of components (e.g. abrasives, lubricants, reinforcements, fillers, modifiers…), each playing a distinctive role in determining the tribology and friction activity of the final friction material. The herein reported work presents novel inorganic “alkali-activated”-based materials suitable for the production of alternative brake linings (i.e. brake pads), by means of an unconventional low-temperature wet process. Exploiting the hydraulic activity of specific components when exposed to an alkaline environment, such peculiar inorganic materials are capable of coming to a complete hardening without the need of traditional high-temperature energivorous procedures.
