“…The Nickel coating on coarse particles by electroless plating method was very well reported but the research on coating of Ultra fine particles was limited [4]. The nano sized ceramic powders have been recognized as effective strengthening second phases for MMCs [7,8].…”

“…The pre treatment of the powder (Sensitization and Activation) makes the conditions favorable for plating. The nickel deposition with SnCl2 sensitization and PdCl2 activation is employed in the present work [2,4]. In the sensitization process, Sn 2+ ions are absorbed on the surface of the Al2O3 powders, which could facilitate attracting of Pd 2+ ions onto the surface of particles (Eq.…”

“…One is surface treatment and the other one is bathing for Plating. The plating through electroless method depends on many process parameters like sensitizing and activating conditions, plating time, pH, Temperature, Stirring, elements and concentration of the bath [4,5,6,7,9,15]. So, the conditions must be good enough for effective plating.…”

“…A few methods like co-precipitation method, sol-gel method are employed to prepare the coated powder [3]. On the other hand, the electroless plating method is another option with an advantage in high deposition rate, simple operation and capability of mass production [4]. Another advantage of using electroless nickel is its ability to produce the deposits with a very high degree of uniformity of thickness [5,9].…”

“…In this method, the electroless coating on the reinforcement particles eliminates the porosity at the interface of metal-ceramic. Recent studies about the electroless coating of nickelboron and nickel-phosphorus on the surface of ceramic particles show that coating requires different activation methods on the particles, such as palladium activation [8]. However, an acceptable morphology and good adhesion of the coating a have not been achieved.…”

Creation of Ni-B/Ni-P electroless coating on the WC particles without surface activator

One of the methods for improving metal-ceramic interface and suppression of agglomeration is the formation of a monolayer electroless coating on the particles. Investigations indicated that Ni-B monolayers should be first formed to develop in the next process an electroless Ni-P coating with the morphology of cauliflower. It was possible to produce a Ni-B layer on WC particles when a bath was heated at a temperature of 95 °C by using sodium borohydride and an appropriate stabilizer. Following this process, the Ni-P electroless coating was deposited on WC particles at 85 °C. In this way, two layers of electroless coating of Ni-B/Ni-P on the WC ceramic particles without using the surface activator were produced successfully. The coating morphology and surface analysis were performed by scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDX). The results showed that only the degreasing with acetone as a surface preparation of ceramic particles is sufficient to make a Ni-P or Ni-B coating. Electroless Ni-B coating with appropriate adhesion to the surface produces an acceptable surface for the electroless Ni -P coating formation.
