Role of Peptone in the Electrodeposition of Tin and Tin-Zinc Alloys from Neutral Gluconate Bath

Tin–zinc electrodeposition from sulphate–tartrate baths

“…In view of their good properties, they have been proposed as substitutes for other industrial coatings, such as those of toxic cadmium and allergenic nickel [1,2]. Tin-zinc electrodeposition has been investigated using different bath systems [3][4][5][6][7][8][9][10][11], at different pH values and using different complexing agents and additives, in order to replace the contaminant cyanide baths used in industrial processes for tin-zinc alloy plating [12]. In some of these studies [3,6,9] it has been reported that alloy coatings with 20-30% Zn by weight have the best mechanical and corrosion protection properties.…”

Electrodeposition of Tin from Tartrate Solutions

“…There is increasing interest in tin used as a substitute for conventional coatings [1][2][3][4] because it has much less environmental impact. Recently published studies on tin and tin-alloy electrodeposition, focus on the influence of either additives, bath compositions or plating variables [5][6][7][8][9][10][11][12][13][14]. In a previous paper [13], the general voltammetric and chronoamperometric characteristics of tin electrodeposition from sulphatetartrate baths was reported.…”

Initial, Stages of Tin Electrodeposition from Sulphate-Tartrate Baths

“…The recent published studies about tin or tin alloy electrodeposition [12][13][14][15][16][17][18][19][20][21][22] are mainly focused in the study of the additives, the bath compositions and the plating variables which permit to obtain coatings for commercial uses, but only few results about the reduction kinetics of Sn(ll) obtained by chronoamperometric techniques were reported [23][24][25][26], In this study, the tin electrodeposition from a sulphate bath using tartrate as chelating agent was investigate by means of potentiodynamic and potentiostatic electrochemical techniques, in order to establish the influence of the electroplating variables in the earlier stages of tin deposit. The model of nucleation and growth of the earlier stages of tin deposits in a sulphate-tartrate bath will be obtained and these results will be compared with those obtained in a sulphate-gluconate bath [26],…”
