متن کاملStructural Characterization and Mechanical Properties of As-plated and Heat Treated Electroless Ni-B-P Alloy Coatings
The Ni-B-P alloy coatings were made autocatalytically (electroless) using an alkaline plating bath with nickel chloride hexahydrate (NiCl2.6H2O) as the source of nickel ions, sodium borohydride (NaBH4) and sodium hypophosphite (NaH2PO2) as reducing agents and source of boron and phosphorous ions, respectively. The effects of bath concentrations on the plating rate, composition of coating, surfa...
متن کاملCORROSION BEHAVIOR OF ELECTROLESS Ni-P/NANOZnO COATINGS
Abstract:Electroless Nickel-phosphorus (EN) coatings provide high performance in various industrial fields due to their unique properties such as excellent corrosion and wear resistance. This paper aims to study the effect of ZnO nano-particles addition on corrosion behavior of EN coatings. Various amounts of ZnO nano-particles with average diameter of 50 nm were added to hypophosphite reduced ...
متن کاملINVESTIGATION OF THE MECHANICAL, CORROSION PROPERTIES AND WEAR BEHAVIOUR OF ELECTROLESS Ni-P PLATED MILD STEEL
In the present study the mild steel (MS) specimens were coated with Nickel-Phosphorus (Ni-P) using acrylic bath. Heat treatment was carried out on specimens under different temperatures and time periods in an inert atmosphere. The various mechanical and tribological tests were performed on specimens. Using weight loss method, the corrosion nature of the samples under different environments was ...
متن کاملShot Peening as an Alternative to Fatigue Life Improvement of CK45 Steel Coated with an Electroless Ni-Cu-P
The effect of an electroless Ni-Cu-P coating on the fatigue behavior of quenched and tempered CK45 steel has been investigated. The fatigue tests under rotating bending conditions have been conducted in three different conditions of uncoated, as-deposited and shot peened prior to the coating deposition. The results indicate that plating of the base steel leads to a fatigue life reduction. The d...
