In this study, Ni-P-SiC composite coatings were prepared by adding different amount of SiC particles into electroless Ni-P plating solution. The effects of SiC particles concentration in solution on depositing rate and composition of the coatings were investigated. The different SiC contents in coatings could be obtained by adjusting the amount of SiC particle concentration in electroless plating solution. Scanning electron microscopy (SEM) results indicate that SiC particles are dispersed in the composite coating and Ni-P alloy is mainly as a bond metal envelope with SiC particles. At the same time, the microhardness became increased and the wear resistance improved with the increasing of SiC content.

Burr in drilling plays an important role on product quality, so analysis the burr size is essential at the final production. This paper presents the application of Taguchi method for survey the burr height and burr thickness by adding ultrasonic vibration to the process. In this paper L18 orthogonal array based on Taguchi techniques was used in the design of experiments. Analysis of Variance (ANOVA) was used to determination the effect of drilling parameter on burr formation. Influence of cutting speed, feed rate and percentage of SiC particle was investigated in with and without Ultrasonic assisted drilling. Al/SiCp MMC with 5, 15 and 20 wt% of particulate SiC in dry drilling operation with TiN coated drill tools were investigated.

Duplex Ni-P/Ni-P-β-SiC coatings were prepared on 2605N double phase stainless steel substrate by electroless plating process. Experiments were carried out to compare and analyze the morphologies, composition and structure of Ni-P/Ni-P-β-SiC by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), XRD and electrochemical workstation, respectively. The results show that duplex Ni-P / Ni-P-β-SiC coating has good associativity between the coating and the substrate, β-SiC particles were uniformly distributed in the coatings, without pores, crack defects and so on. When β-SiC particle concentration is 15g/L, the microhardness reached maximum 623.285HV0.20, In addition, when the β-SiC concentration is 15g/L, the corrosion reasistence is the best.
