Research Into Temperature Dependence of Some Physical Characteristics of Thermostable Nickel Coatings on Aluminum Alloys

Research into some electric and mechanical characteristics (specific resistance, Yung modulus, internal friction) of electrolytic nickel coatings obtained from nickel plating persulphate solution on aluminum base before and after thermal treatment is presented in the paper. It revealed that following thermal treatment operation properties of the coating increases, adhesion improves and inter-granular distance decreases. Coatings obtained may be used for functional purposes in different technologies.
