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

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 microstructure test. Taughi method using to select the best values of Micro-hardness and corrosion from the samples. [ABSTRACT FROM AUTHOR]
