The effect of wax-containing microcapsules incorporated in silicone composite coatings deposited on aluminum (Al) alloy substrates on the tribological performance of the coatings was systematically investigated. The wax-containing microcapsules were prepared via in situ polymerization. The tribological behavior of the composite coatings was evaluated using ball-on-disk tribological test. It was...

Tribological coatings made of MoS2 and WSe2 phases and their corresponding combinations with tungsten carbide (WC) were prepared by non-reactive magnetron sputtering of individual targets of similar composition. A comparative tribological analysis of these multiphase coatings was done in both ambient air (30-40% relative humidity, RH) and dry nitrogen (RH<7%) environments using the same tribome...

The tribological understanding of friction and wear mechanisms and the generation of reliable friction and wear data are of increasing importance for the determination of reliability of machinery and availability of plants and transportation systems. To be of real value in reliability engineering, the tribological data should be expressed in terms of endurance life and probability of failure. T...

Ion implantation has been widely used to improve the mechanical and tribological properties of single crystalline silicon, an essential material for the semiconductor industry. In this study, the effects of four different ion implantations, Ar, C, N, and Ne ions, on the mechanical and tribological properties of single crystal Si were investigated at both the nanoscale and the microscale. Nanoin...

A new stratified approach to pre-clinical tribological simulation of joint replacements is presented, which extends beyond present standard conditions used. It includes variations in surgical delivery, variations in kinematics, variations in the patient population and degradation of the biomaterials technology. Examples of the new methods are presented, which have been validated against clinica...

INTRODUCTION Titanium alloys are applied as the preferred endplate materials for artificial cervical disc because of their good mechanical properties, prominent biocompatibilities and corrosion resistance [1]. However, the poor tribological performances of titanium alloys might cause aseptic loosening and the osteolysis, which could lead to the failure of the replaced cervical disc implants [2,...

M. Madej, D. Ozimina, Kielce University of Technology, Poland R.Gałuszka, The Jan Kochanowski University in Kielce, Poland G. Gałuszka School of Economics, Law and Medical Sciences in Kielce, Poland The a C:H:W, TiN/a C:H:W and the CrN/a C:H:W coatings were deposited on steel surface by physical vapour deposition methods and studied for corrosion and tribological properties, after elemental and...

This work studied the development of vegetable based lubricants and the addition of oxides nanoparticles (ZnO and CuO) as additive for extreme pressure (EP), exploring the EP and oil base influence in tribological behavior. The results showed that with the addition of nanoparticles to conventional lubricant, the tribological properties can be significantly improved. A smoother and more compact ...

Intermetallic compounds are increasingly being expected to be utilized in tribological environments, but to date their implementation is hindered by insufficient ductility at low and medium temperatures. This paper presents a novel multiphase intermetallic alloy with the chemical composition of Mo-40Ni-13Si (at %). Microstructure characterization reveals that a certain amount of ductile Mo phas...

A numerical, tribological data collection system with 15,000 data records was developed to find materials for tribological operations. The database enables the user to search, retrieve and display information and data about the appropriate material couples in a fast and convenient way. The database is intended to be used by researchers, engineers, consultants and developers. All tribological ch...
