Enhancement of the corrosion protection of electroless Ni–P coating by deposition of sonosynthesized ZnO nanoparticles

As an important basic material of electronic equipment, copper (Cu) foils should have a small thickness, good mechanical properties, and excellent thermal conductivity. However, preparing an ultrathin Cu foil with good properties remains challenging. Herein, we report an electroless deposition (ELD) strategy for the facile and scalable preparation of an ultrathin freestanding nickel-coated graphene (NCG)/Cu composite foil in a short time of 25 min. The NCG can significantly improve the mechanical and physical properties of composite foils. Experimental results reveal that the NCG/Cu composite foil manifests the best performance when the NCG concentration in an ELD bath was 30 mg/L. The composite foil evidenced a thickness of 1.1 μm, a high tensile strength of 338.7 MPa, and a high thermal conductivity of 431.2 W/mK. Compared with the pure Cu foil, both bending times and elastic modulus are increased by 298.1 and 737.3%, respectively. Remarkably, the composite foil has excellent heat dissipation performance, showing enormous potential as a heat sink material. This work proposes a new method for manufacturing the ultrathin graphene-reinforced Cu composite foil with high performance for numerous applications.

“…A good example of how flow of electroless plating solution affects the deposit is the study (Sharifalhoseini & Entezari, 2015) where it was found that the Ni-P deposition rate onto mild steel was higher when the sample was positioned horizontally with respect to the ultrasonic probe as opposed to vertical (see Table 5.2). In addition to this, from the present literature survey no two papers using similar power (W) and frequency (kHz), and different plating solution conditions (i.e.…”

Ultrasound waves generate and enlarge gas cavities in an aqueous solution by compression and rarefaction cycles. When cavities have grown to a certain size they become unstable and collapse under external pressure. This process leads to a number of effects such as standing waves, microjetting, localized temperature increases etc., which can have a positive effect on electrochemical and chemical systems. In this chapter research studies concerning electroless nickel (Ni) deposition by ultrasound are reviewed. The main benefits of using ultrasound assisted electroless Ni deposition include (1) increased rate of deposition, (2) modification of coating morphology (3) modification of coating composition (4) dispersion of particles for composite deposition and formation of core-shell particles and (5) improved coating uniformity on complex structures.

ABSTRACTEFFECT OF TEMPERATURE AND HEATINGTIME ON THE COATING CHARACTERISTICS OF MARTENSITIC SS 420 ELECTROLESS Ni-P. Electroless nickel phosphorus (Ni-P) coating has been done on the martensitic stainless steel SS 420 with a variety of temperature and heating time. Electroless Ni-P coating characteristics; microstructure and corrosion resistance were analyzed to determine the effect of variations in temperature and heating time. Variations in the temperature of the heat treatment used are 200
