Any metal that can be made into a fine powder can be mechanically plated, however CIP specializes in zinc, tin, and aluminum.

ASTM B Mechanical Galvanizing Zinc Plating

Is there an ASTM that provides a standard for the high-build organic coating? Sacrificial metal coating is applied with coverage to all surfaces of the part satm the corners recesses, threaded areas as well as to the flat, more exposed regions.

Because of the composite nature of mechanical coating, this naturally lubricated coating will not gall, producing more accurate torque-tension relationship.

Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. Download Now White Paper: 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.

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. Excellent Adhesion and controlled uniformity of coating thickness: Click here for a quote or call us at 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.

The ability to plate flat parts: CIP is certified to work with coating for zinc deposited mechanically onto iron and steel basis metals. Defense manufacturing is all about project manufacturing and project accounting. V695 most important reason for mechanical plating is the assurance of product reliability through the elimination of hydrogen embrittlement.

The zinc coatings are classified according to thickness asttm identified into two types; as coated without supplementary treatments or with colored chromate conversion treatment. Even if the mechanical plating finish is scratched, there is still galvanic protection for the base metal. Mechanical plated arts can be given post plate treatment of dichromate dye for color-coding and phosphate for improved paint adhesion and waxing.

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. Link to Active This link will always route to the current Active version of the standard. atm

Historical Version s – view previous versions of standard. This abstract is a brief summary of the referenced standard. Nonmagnetic Coatings on Magnetic Basis Metals. Resources Digital Transformation may be defined in a number of different ways by analysts or enterprise axtm vendors. Samples should be tested for adhesion, salt-spray corrosion resistance, appearance, thickness, and absence of hydrogen embrittlement.

Join your peers on the Internet’s largest technical engineering professional community. Appearance is uniform comparatively smooth with a satiny texture and has none of the discolored and mottled effect o hot-dip galvanizing. It’s easy to join and it’s free. The mechanical plating process takes place in a tumbling barrel filled with tumbling media e. In hot-dip b95, molten zinc often b95 parts together, resulting in lost time, effort and materials.

Mechanical plating has the ability to plate sintered metal parts powder metallurgy without costly impregnation. Plating does not require the added production step and cost of non-reliable post plated baking, as is the case with electroplating. Work Item s – bb695 revisions of this standard. Overall appearance of mechanical galvanizing is superior to the overall appearance of hot galvanizing.

Deburring is a bonus: In hot-dip galvanizing, threads must be cut or chased after galvanizing, robbing them asttm protection and requiring extra expense. Mechanical plating is he method preferred by many engineers for hardened fasteners and stressed components. For equivalent thickness, mechanical galvanized is equal or superior to conventional galvanizing methods. The base metal is less chemically active s o that the coating corrodes first.

Hydrogen embrittlement is a phenomenon which causes materials to lose their strength and become brittle.

Mechanical Plating & Galvanizing

Batch to batch conformity: The ability to plate zinc, cadmium, tin or lead any mixture of these materials. The mechanical plating process is a process in which fine metal powders are cold welded to metal components without electricity and without heat. The main advantage of mechanical plating over electroplating is the elimination of hydrogen embrittlement.

Thermal spray probably aluminum would be better than paint for marine exposure. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of n695 limitations prior to use. Mechanical Galvanizing does not fill valleys of threaded fasteners and their parts mate quickly and easily.
