Crack-free Cu alloy coating has been fabricated on Al substrate with the existence of a Ag buffer layer. The had 12 at.% and 45 Ag, which contributed to formation solid solution eutectic phase (transformation temperature 780 °C). was characterized as finer solution. layer main contents Ag2Al solution, it not only hindered brittle intermetallic compounds (IMCs)but also reduced thermal stress its...

the effect of an electroless ni-cu-p coating on the fatigue behavior of quenched and tempered ck45 steel has been investigated. the fatigue tests under rotating bending conditions have been conducted in three different conditions of uncoated, as-deposited and shot peened prior to the coating deposition. the results indicate that plating of the base steel leads to a fatigue life reduction. the d...

Self-healing polymers composed of microencapsulated healing agents exhibit remarkable mechanical performance and regenerative ability, but are limited to autonomic repair of a single damage event in a given location. Self-healing is triggered by crack-induced rupture of the embedded capsules; thus, once a localized region is depleted of healing agent, further repair is precluded. Re-mendable po...

The new types of knowledge-intensive, multilayer containers consist of steel plates protected against corrosion by nanometric electrolytic chromium (Cr0) and chromium oxide (Cr2O3) layers chemically bonded to polyethylene terephthalate (PET) polymer coating to preserve food. It was observed that after emptying the cans, the salmon adhered to the polymer coating, changing its color, and that thi...

In the present study, the effects of growth defects and chromium content loss on the degradation of corrosion and passivation of cathodic arc evaporation (CAE-PVD) of stainless steel coating were investigated in 2 M sulphuric acid solution. EDS analysis indicated that the micro-particles were obtained during the coating growth. In addition, it was detected that the growth defects had poor adhes...

The inherent reactivity of Al–Cu–Mg alloys is such that their use for building structural, maritime, and airplane components with great strength/weight ratios would not be possible without good anti-corrosion systems. These systems could considered as imitations the protection mechanism found in conventional hexavalent chromium-based system, but additional limited environmental impact, particul...

BACKGROUND One of few persisting problems of cemented total knee arthroplasty (TKA) is aseptic loosening of tibial component due to degradation of the interface between bone cement and metallic tibial shaft component, particularly for surface cemented tibial components. Surface cementation technique has important clinical meaning in case of revision and for avoidance of stress shielding. Degrad...
