A molybdenum boride (MoB) coating was prepared on molybdenum (Mo) by an in-situ chemical vapor deposition method. To develop a fuller understanding of the effect of depositional conditions on the growth of MoB coating formed on Mo substrate, this paper studied the phase composition and microstructure of the coating at varied conditions. At the same time, the relationships between the growth of ...

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...

Improving the interfacial stability between cathode active material (CAM) and solid electrolyte (SE) is a vital step toward development of high-performance solid-state batteries (SSBs). One challenges plaguing this field an economical scalable approach to fabricate high-quality protective coatings on CAM particles. A new wet-coating strategy based preformed nanoparticles presented herein. Nonag...

several investigations have been devoted towards understanding the coating process in fluidized beds. most of these studies focused on spraying liquid droplets over the bed. however, due to the complexity of these systems, more investigations are still required to quantify the effect of operating conditions on the coating criteria. the present work aims at fundamentally understanding and precis...

Researchers have been focused on the influences of flowing fluid on the corrosion of bare metals, but there is little emphasis on the degradation of metal-protective coating. Evaluating the metal-protective coating usually uses the Electrochemical Impedance Spectroscopy (EIS) method. EIS is a technique used for evaluating coating permeability or barrier performance based on the electrical imped...

Novel scaffolds composed of poly(L-lactic acid) (PLLA) skeleton covered with bonelike apatite or apatite/collagen composite were produced via a combined phase-separation technique and an accelerated biomimetic coating process. Saos-2 osteoblast-like cells were used to evaluate the cellular behaviors on these biomimetic coatings. Cell morphologies on the surfaces of PLLA scaffolds, PLLA scaffold...

in this research, b4c-ni cermet coating was sprayed on the surface of 4130 steel from b4c and ni feed-stockpowders using high velocity oxy-fuel (hvof) method. in order to characterize the tribological behavior of thecoating, ball on disk wear tests were done at the ambient temperature and under the loads of 1, 3 and 5 n.phase analysis of the coating after spraying was studied by x-ray diffracto...

The polysaccharide based composite biomaterial (coating) used in preserving fruits and vegetables during storage is attracting increased attention as it biodegradable material that prolongs shelf life. In the present investigation, chitosan–pullulan (50:50) edible coating was prepared with pomegranate peel extract (0.02 g/mL) an active antioxidant agent. effect of treatment enriched on life man...
