The Electrochemical Metallizing is a portable method to electroplate several metals and alloys without the need to immerse the part in a bath.   How does it work? It uses a specially designed power unit and tool that operates as an inert anode. This is then wrapped with an absorbent material and wet with a specially formulated solution containing the desired metal or alloy. The part is connected to the negative terminal and the tool to the positive. When the tool contacts the part, the circuit is closed and deposition begins.   What is it used for? Cold dimensional restoration of worn or mismachined parts. Even on site. Protection against wear, corrosion or temperature by localized layers of appropriate metals. Provide good solderability, increase conductivity, repair damaged plating, etc.     Advantages over other methods? Selective deposit (ideal for very large parts or with localized defects). Molecular adhesion. Thickness accurately controlled. Portable equipment. Very fast compared with other build up methods (in layers less than 0.008” thick). Smooth finish (reproduces the original). Layers up to 0.030” thick or more of the soft metals. For hard metals such as nickel, cobalt or tungsten 0.001 a 0.002” is the maximum.   Fig.1. diagram OF THE  ELECTROCHEMICAL METALLIZING Fig.2. APLICATION OF THE PROCESS TO A DAMAGED MACHINE WAYBED       NIQUEL ® AUTOCAT (Back) What is it? The Autocat ® Niquel Process  is a high  technology method to coat a part by immersion without the application  of electric current. It applies a uniform layer of a nickel alloy to the whole surface that is in contact with the liquid, regardless of its geometry, position in the tank, surface condition, etc.   What advantages does it have? It is the only metallization process to provide total layer uniformity and penetration with considerable thickness (normal 1 to 3 mils., max. 10 mils.). In most cases it does not require grinding or final operations, as is almost always the case with thermospray metals or hard chrome. It resists more corrosion than the later, especially in presence of chlorides  (Fig. 1). Its hardness of 50 Rc is very sufficient for most applications but, if necessary, it can be increased to 69Rc by a low temperature heat treatment. (Fig.2)   What is it used for? It is an engineering coating normally selected because of its outstanding resistance to corrosion, wear, and anti sticking properties. It is applied to molds, dies, tools, food handling parts, rolls, piston rods, oil equipment, in the automotive, plastic, and paper industries, in electronics, printing, textile equipment, etc.
