Factors Effecting on Nano-composite Coating (Ni-P-CNTs) Under Hardness and Corrosion by ANOVA

Abstract

Electro- less Nano-coating of Ni– P  was mixed with  carbon nano tube (CNTs) and then deposited on low carbon steel  substrate. Electro- less Nano-coating was done using different temperatures and times.  Nickel  (Ni) was added by 4.4 wt.%, phosphore (P) was added by 4.2 wt. %. While carbon nano tube (CNTs) was added various  content  by 2wt.% and 3Wt%. The results  of this work showed that  the surface micro-hardness  for CNTs increases with decreasing time and temperature which is 450 Hv for. While the rate of corrosion had different results  but the best  was 0.265 according to Taughi selection. The microstructure of the deposite coating of Ni–P was analyzed  by micro-structure test . Taughi method using to select the best values of Micro-hardness and corrosion from the samples.
