Apparently, this ASTM standard uses a mechanical means qstm place zinc onto the metal surface and b659 approach is reported to be better then the hot dip method which can have the zinc flake off. The ability to plate flat parts: CIP is certified to work with coating for zinc deposited mechanically onto iron and steel basis metals.
Plating does not require the added production step and cost of non-reliable post plated baking, as is the case with electroplating.
ASTM B for coating of Zinc mechanically onto IRON/STEEL. – Corrosion engineering – Eng-Tips
Promoting, selling, recruiting, coursework and thesis posting is forbidden. Is there an ASTM that provides a standard for the high-build organic coating? For equivalent thickness, mechanical galvanized is equal or superior to conventional galvanizing methods. The tumbling action during plating provides some deburring of parts and saves you money. Neither will be great b659 long-term marine exposure, I would suggest a high-build organic coating system probably with a zinc-based primer or thermal spray zstm layer.
Historical Version s – view previous versions of standard. We, as qualified professionals, can plate low carbon steel, asm rolled steel, high carbon heat-treated steel, various tool steels, high strength alloys, free-mechanical steels including leaded steels.
Deburring is a bonus: 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.

Mechanical Plating & Galvanizing
Mechanical plated arts can be given post plate treatment of dichromate dye for color-coding and phosphate for improved paint adhesion and waxing. This mechanical plating process characteristically makes this technology an ideal choice for plating hardened steel springs.
Mechanical Galvanizing does not fill valleys of threaded fasteners and their parts mate quickly and easily. 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. Thickness depends only on the amount of zinc powder.
Mechanical Plating – ASTM B Mechanical Galvanizing | Custom Industrial Processing
In hot-dip galvanizing, molten zinc often fuses parts together, resulting in lost time, effort and materials. Because of the composite nature of mechanical coating, this naturally lubricated coating will not gall, producing more accurate torque-tension relationship.
Digital Transformation may be defined in a number of different ways by 6b95 or enterprise software vendors. Download Now White Paper: The ability to plate zinc, cadmium, tin or lead any mixture of these materials. The zinc coatings are classified according to thickness and identified into two types; as coated without supplementary treatments or with colored chromate conversion treatment. CIP offers two post-plating services: Mechanical plating has the ability to plate sintered metal parts powder metallurgy without costly impregnation.
