Mechanical Galvanizing produces parts that are ready to use without any further processing steps.

Electroplating Mechanical Galvanizing vs. Sacrificial metal coating is applied with coverage to all surfaces of the part to the corners recesses, threaded areas as well as to the flat, more exposed regions.

No time variables common with hot-dip. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

Historical Version s – view previous versions of standard. It’s easy to join and it’s free. Work Item s – proposed revisions of this standard. Apparently, this ASTM standard uses a mechanical means to place zinc onto the metal surface and this approach is reported to be better then the hot dip method which can have the zinc flake off.

Thickness depends only on b95 amount of zinc powder. Are you an Engineering professional? This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text adtm the standard itself must be referred to for its use and application.

Mechanical plating has the ability to plate sintered metal parts powder metallurgy without costly impregnation. Surface protection guide for steelwork exposed to atmospheric environments ht tp: CIP is certified to work with coating for zinc deposited mechanically onto iron and steel basis metals.

This makes mechanical plating an ideal process for plating flat stampings and washers. If an application requires torqueing, exposure to vibration or any handling that could rupture a finish, mechanical plating provides durable metal coating with excellent adhesion.

The inch-pound equivalents of SI units are given for informational purposes. Samples should be tested for adhesion, salt-spray corrosion resistance, appearance, thickness, and absence of hydrogen embrittlement. Threaded peaks especially show no build-up plating thickness.

Mechanical Plating & Galvanizing

Even if the mechanical plating finish is scratched, there is still galvanic protection for the base metal. Register now while it’s still free! They or other sharp points have uniform thickness you want in plating. Batch to batch conformity: Hot Dip Galvanizing Resin Impregnation.

Mechanical Galvanizing is a room temperature process that does not detemper heat-treated parts. The thickest coating classes are usually referred to as “mechanically galvanized”. Because mechanical plating is so uniform, you can save money by coating at lower average thickness. Hot dip galvanising is generally more durable and sturdy than mechanically applied zinc layers. Promoting, selling, recruiting, coursework and thesis posting is forbidden. Defense manufacturing is all about project manufacturing and project accounting.

Mechanical plating is he method preferred by many engineers for hardened fasteners and stressed components. Download Now Defense manufacturing is all about project manufacturing and project accounting. 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 mechanical plating process takes place in a tumbling barrel filled with tumbling media e. This specification covers the requirements for zinc coatings that are mechanically deposited on iron or steel basis metals. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided sstm part of the standard.

Electroplating The main advantage of mechanical plating over electroplating is the elimination of hydrogen embrittlement.
