“…In the second stage of numerical experiments, the calculations of the roughness parameter were carried out for the condition of minimum friction coefficient by dependence (5) and for the case of no film starvation by inequality (8) in the presence of cylindrical and spherical waviness for two kinds of friction pairs studied. Ratio S/(S − d) varies according to the condition (10) when the nominal contact pressure is in the range of p a = 2-40 MPa.…”

The theoretical study and evaluation of stress-strain condition of the friction pair's surfaces of total hip joint prosthesis with partially regular texture on a ball head surface, depending on the values of its characteristic parameters, using finite element modeling are performed. It has allowed formulating the recommendations for dimple's spacing rationing and the extent of a surface rough site with partially regular texture, aiming to increase the prosthesis' lifespan. The problem is solved from the condition of dry or boundary lubrication. For the indicated range of nominal contact pressure in hip joint, the quantitative evaluation of allowable roughness parameters to which it is necessary to process the ball head surface for metal-on-metal and metal-on-polymer friction pairs are obtained, considering the dimple's spacing and size on the surface.

“…But it may not be quite the right decision in the case of couple containing the polymer element as a mating surface. One of the ways of decreasing the intensity of wear and localisation of its products in sliding couple is known method of texturing one of surfaces of the couple [5].…”

“…Dimple density was therefore designed so as to act similarly to such solid lubricant inserts, as it is assumed that the dimples can act as lubricant reservoirs, slowly releasing lubricant into the contact. The study of the influence of dimples geometry, density and array type are discussed in other works in literature [ 38 , 39 ] and was beyond the scope of this paper.…”

In heavy loaded mating components, such as sliders and sliding bearings, guaranteeing the efficiency of lubricant films for long times during severe service conditions is very complicated. In this work, the benefits deriving from the use of fiber laser sources for surface texturing of very thin TiN coatings in severe wear working conditions were demonstrated. Evaluations of the laser textured dimples shape, geometry and density are given. Wear performance of the fiber laser textured surfaces was evaluated in discontinuous oil lubricated conditions with a flat contact. High normal load and low sliding speed were applied. Comparison tests were also performed on commercial TiN and WC/C coatings. In terms of average wear volume and maximum wear depth, Laser Surface Texturing of TiN provided respectively a 70% and a 45% reduction if compared to plain TiN. If compared to WC/C the wear resistance gains were lower but LST TiN maintained such benefits for longer wear runs. SEM analysis also revealed that the laser interaction provided a localized thermal cracking to the TiN coating. However, the sliding action caused very limited and localized coating fragmentation or delamination.

Introduction: bio-inspired surface textures-nature's tool for delivering functional surfaces 'It is not the strongest of the species that survives, nor the most intelligent, but the most responsive to change,' said Charles Darwin. Survival of the fittest is a famous phrase of Herbert Spencer, which describes the idea that, in nature, there is a competition to survive and reproduce. Survival and change are two critical terms, especially as species on earth over millions of years are in continuous combat with changing environments. These environments are typically harsh for organisms to live in, but despite these difficulties organisms have survived and thrived by building harmonic ecosystems within divergent environments including marshy and muddy; deep cold and snowy; hot, dry and desert; and more. Living organisms interact and interface with their surroundings through their outer layers, their surfaces which have adapted and evolved with novel but simple designs and functional properties in this process of combat and survival.The surface (and sub-surface) of an organism, also called skin, is an important interface between an organism and its environment, serving a mission critical role in the process of adaptation and survival. Skin surfaces interact with aggressive environmental factors such as temperature, moisture, abrasive agents such as sand and ice, pH, bacteria and viruses, light, mating abrasive or super smooth surfaces, etc. and their combinations. To combat these aggressive factors, skins have evolved unique design architectures that achieve multifunctional properties including (but not limited to) adhesion, hydrophobicity, hydrophilicity, thermal-management, anti-reflection, structural colors, and spherical vision as highlighted in Fig. 1.The skins of organisms, from here onwards called surfaces, deliver these environment-specific properties by combining textures and material chemistries to exploit classical laws of physics to achieve superior functional properties. The term surface texture captures various facets of a construct including the repetitive arrangement of features, the various shapes and sizes of features (in 2-D and 3-D), and the hierarchical distribution of quasi-periodic connected structures in a multi-dimensional space CIRP Annals -Manufacturing Technology xxx (2018) xxx-xxx
