Originally published in 1980, this paper was the second on AES Research Project #41, plating on aluminum, at the National Institute for Science and Technology. A study of the morphologies of zinc and tin immersion deposits on Al and its alloys showed that zinc formed epitaxial deposits on alloys, as noted on pure Al. Similarities exist between the zincate and stannate processes; in particular, the same crystallography orientations are active in both systems. Comparisons between zinc deposits produced from solutions containing ferric chloride and Rochelle salts and deposits from the same solution without these additions show that ferric chloride plays a fundamental role in the deposition process.
Originally published in 1978, this paper was the first of several on AES Research Project #41, a study of plating on aluminum, at the National Institute for Science and Technology. A review of immersion pretreatments for the plating on aluminum is presented. The zincate pretreatments dominate the literature, but innovations were reported which offer improved adhesion and corrosion performance. Finally, an updated bio on Dr. Lashmore’s work through the years is offered.
