“…This contradiction is because increasing sliding distance generally leads to an increase in the real area of contact and a reduction of the applied load at the interface and on the particles present at the interface. Therefore, the slope of the linear relationship may decrease due to longer sliding distances [45]. This seemed to true in the current study where the applied loads were 1N or exceeded this value.…”

Stainless steel is widely used as dental implant. However, there has been little work on the micro-abrasion of such materials in laboratory simulated oral environments, where abrasion, sliding wear can interact simultaneously. In this study, the effects of applied load, and exposure time were evaluated for a 316 stainless steel in a laboratory simulated artificial saliva. Polarization curves showed an enhancement of corrosion current density with increases in applied load. Wear maps were produced showing low wear safety regimes at intermediate loads and exposure times. Possible reasons for such trends are interpreted in terms of the ability of the passive film in providing resistance against third body particle impact and the concentration of particles in the contact at higher loads

“…The analysis methods described below are innovative and are based on characterizing the micro-scale surface topology of the articular cartilage. Local variations in the height of the articular cartilage are measured as a wave function, as in standard surface topology analysis, yielding wave formalism that can be used for the characterization 28 . We provide extensive details because, to the best of our knowledge, this is the first time that such a method has been used to analyze osteoarthritic articular cartilage.…”

Osteoarthritis (OA) is a common degenerative disease whose early management includes promising mechanical treatments. New treatments are initially validated using an animal model in which OA is induced. The MMT (mechanical induction) and MIA (chemical induction) models of OA induction are widespread, but their use to generate early OA is poorly documented. We analyzed and compared early-stage knee OA-induction via these two methods in 16 rats divided into two groups. After 4 weeks of induction, the knees were sampled and studied using both histology (Toluidine Blue and Sirius Red) and surface topology, an innovative technique for characterizing osteoarthritic cartilage. The Mankin-modified score confirms that the two OA-induction models evolved at the same speed. At this early stage, the two models can be differentiated morphologically, although no significant differences were revealed by either cellularity or birefringence analysis. However, the topological analysis generated two forms of quantitative data, the deformation ratio and the cohesion index, that differentiated between the two groups. Thus, the early-stage OA induced by these two models is revealed to differ. The patterns of cartilage damage induced point to MMT as the better choice to assess mechanical approaches to clinical OA treatment.

“…Physically, this result is consistent with the explanation that the adhesive is squeezed out from the small spots where the crests of the mating rough surfaces clash together and is accumulated in the surrounding voids. In this way, the intermetallic junctions provide the same frictional strength (proportional to the contact pressure [8]) as in the dry joint, while the surrounding adhesive bonds provide a strength contribution (irrespective of the pressure) similar to that of the purely adhesive interface.…”

This paper deals with the static strength of mechanically tightened joints augmented with anaerobic adhesives. Tests were performed on a variety of specimens distinguished by fairly homogeneous (annular butt joint) or realistically inhomogeneous (threaded, cylindrical and double lap joints) working conditions over the bondline. For each geometry, the strength of the dry (unbonded) joint was compared with the strength of the joint bonded with an assortment of anaerobics. The results indicate that the strength of all joints (bonded and unbonded) increases with the contact force. When strong adhesives (retainers) are used, the overall strength approximately equals the sum of friction and adhesive strengths, taken separately. When weak adhesives (threadlockers) are adopted, the superimposition of effects grossly overestimates the measured strength. A micromechanical model is proposed that explains the observed macroscopic behaviour.
