Red Flag This Post Please let us know here why this post b69 inappropriate. Even if the mechanical plating finish is scratched, there is still galvanic protection for the base metal.

Mechanical plating is he method preferred by many engineers for hardened fasteners and stressed components. Mechanical Galvanizing produces parts that are ready to use without any further processing steps.

Because Mechanical Galvanizing is an extension of mechanical plating technology; it does not produce hydrogen embrittlement and does not require lengthy non-reliable post-plate baking cycles. This specification covers the requirements for zinc coatings that are mechanically deposited on iron or steel basis metals.

This mechanical plating process characteristically makes this technology an ideal choice for plating hardened steel springs. The thickest coating classes are usually referred to as “mechanically galvanized”. They or other sharp points have uniform thickness you want in plating.

ASTM B – 04 Standard Specification for Coatings of Zinc Mechanically Deposited on Iron and Steel

It’s easy to join and it’s free. The mechanical plating process takes place in a tumbling barrel filled with tumbling media e. Hot dip galvanising is generally more durable and sturdy than mechanically applied zinc layers. Hydrogen embrittlement is a phenomenon which causes materials to lose their strength and become brittle.

Also – My application are exposed structural steel members that are placed in GUAM heavy salt marine environmentwhich method would you use for corrosion protection OR if you know of a better way for corrosion protection, please share it.

Excellent Adhesion and controlled uniformity of coating thickness: Mechanical Galvanizing does not fill valleys of threaded fasteners and their parts mate quickly and easily.

For equivalent thickness, mechanical galvanized is equal or superior to conventional galvanizing methods. Threaded peaks especially show no build-up plating thickness. The mechanical plating process is a process in which fine metal powders are cold welded to metal components without electricity and without heat. Custom Industrial Processing, Inc. Digital Transformation may be defined in a number of different ways by b69 or enterprise software vendors.

The most important reason for mechanical plating is the assurance of product reliability through the elimination of hydrogen embrittlement. Register now while it’s still free!

It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. Historical Version s – view previous versions of standard. Thickness depends only on the amount of zinc powder.

Parts breakages because of hydrogen embrittlement need not be a problem of parts are plated mechanically and are not used for a minimum of 48 hours after plating. The tumbling action during plating wstm some deburring of parts and saves you money.

Mechanical plated arts can be given post plate treatment of dichromate dye for color-coding and phosphate for improved paint adhesion and waxing. Students Click Here Join Us! We, as qualified professionals, can plate low carbon steel, cold rolled steel, high carbon heat-treated steel, various tool steels, high strength alloys, free-mechanical steels including leaded steels.

We also work with both Type I as ast, without supplementary treatment and Type II with chromate conversion treatment B specifications for special processing needs.
