Chapter 14 DOI: 10.4018/978-1-5225-0066-7.ch014 ABSTRACT Electrodeposition of only molybdenum onto substrates is difcult, therefore molybdenum is typically deposited with iron-based alloys such as nickel. The deposition of such alloys is known as an induced codeposition mechanism. The electrodeposition of nickel-molybdenum alloys using alkaline plating solu- tions is covered in this chapter. The mechanism for deposition of nickel-molybdenum is reviewed, as well as the infuence of the plating parameters on the coatings. Characterization of the coatings by scanning electron microscopy and x-ray difraction is discussed and how deposition parameters afect morphol- ogy, composition, and crystallite size. Nickel-molybdenum alloys ofer enhanced corrosion protection and mechanical properties as coatings onto various substrates. A survey of the resulting hardness and Young’s modulus is presented for several research studies. Corrosion parameters for several studies are also compared and show the percentage of molybdenum in the coatings afects these values. INTRODUCTION Stainless steels are corrosion resistant in a wide range of environments due to formation of a passivating film on their surfaces. Despite passivity, extensive localized corrosion commonly occurs on stainless steels when exposed to harsh environments containing chloride ions, such as seawater.
