In this paper we will demonstrate how a thermodynamic-kinetic method can be utilized to rationalize a wide range of interfacial phenomena between Sn-based lead-free solders and Ni metallizations. First, the effect of P on the interfacial reactions, and thus on the reliability, between Sn-based solders and electroless Ni/immersion Au (ENIG) metallizations, will be discussed. Next, the effect of ...
in this work the effects of various methods of agitation on the properties of electroless ni-p-mos2 composite coatings were investigated. magnetic stirring as well as purging the solution with gas (air, oxygen, nitrogen) were used. plating rate, chemical composition, mos2 distribution, and hardness of the deposit were measured. topography of coating was studied with metallography and scanning e...
in the present study, ni-p-cnt composite coating was successfully fabricated via electroless plating. scanning electron microscopy (sem) was used to characterize the coatings. the effect of cnts concentration in the bath on its content in the composite coatings was studied. furthermore, the corrosion behaviour of the coatings with different contents of cnts was evaluated using tafel polarizatio...
An electroless plating of Co-Ni-P was applied to a grain-oriented electrical steel substrate resulting in a power loss improvement of approximately 9-11 %. The mean thickness of the coating was found to be 2.15±0.15 μm from Environmental Scanning Electron Microscope (ESEM) images. Shifts of the magnetostriction stress sensitivity curves showed that stress was acting on the substrate corroborate...
In this report, vulcan XC-72 supported PtNi alloy catalyst nanoparticles were synthesized by electroless deposition method using NaBH4 as a reduction agent. The properties of the synthesized Pt-Ni/C catalysts were investigated and evaluated. Transmission electron microscopy (TEM) results showed that PtNi alloy catalysts dispersed well on the carbon supports and their particle size was in the ra...
