Because of the composite nature of mechanical coating, this naturally lubricated coating will not gall, producing more accurate torque-tension relationship. The zinc coatings are classified according to thickness and identified into two types; as coated without supplementary treatments or with colored chromate conversion treatment.

For equivalent thickness, mechanical galvanized is n695 or superior to conventional galvanizing methods. Because mechanical plating is so uniform, you can save money by coating at lower average thickness. 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. Even if the mechanical plating finish is scratched, there is still galvanic protection for the base metal.

Deburring is a bonus: The ability to plate flat parts: Once the plating reaches the desired thickness the parts are then dried and post-plating finishes are applied if required.

CIP is certified to work with coating for zinc deposited mechanically onto iron and steel basis metals. The base metal is less chemically active s o that the coating corrodes first. Link to Active This link will always aastm to the current Active version of the standard.

The thickest coating classes are usually referred to as “mechanically galvanized”. Overall appearance of mechanical galvanizing is superior to the overall appearance of hot galvanizing. They or other sharp points have uniform thickness you want in plating.

Historical Version s – view previous versions of standard. 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. Hot Dip Galvanizing Resin Impregnation. Asym tests results should comply with the given requirements. You get the benefit of metallurgical bond and the iron-zinc intermetallics formed by dipping into molten zinc at high temperature.

Mechanical plating has the ability to plate sintered metal parts powder metallurgy without costly impregnation.

Thank you for helping keep Eng-Tips Forums free from inappropriate posts. 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.

The xstm plating process is a process in which b65 metal powders are cold welded to metal components without electricity and without heat. The media prevents flat parts from masking one another, making sure that all surfaces are plated. Custom Industrial Processing, Inc. Parts weighing up to three pound and measuring with a longest dimension up to eighteen inches can be handled, including some that are usually rack excessive build-up o plating on protruding points of the part and leave other areas with thinner spot more vulnerable to corrosion.

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

Resources Digital Transformation may be defined in a number of different ways by b69 or enterprise software vendors. Electroplating Mechanical Galvanizing vs. Any metal that can be made into a fine powder can be mechanically plated, however CIP specializes in zinc, tin, and aluminum. Electroplating The main advantage b6995 mechanical plating over electroplating is the elimination of hydrogen embrittlement. Download Now White Paper: In hot-dip galvanizing, threads must be cut or chased after galvanizing, robbing them of protection and requiring extra expense.

Nonmagnetic Coatings on Magnetic Basis Metals.

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. The inch-pound equivalents of SI units are given for informational purposes. Mechanical Galvanizing does not fill valleys of threaded fasteners and their parts mate quickly and easily.

Uniformity of thickness depends on part size and shape with typically thinner deposits on edges and thicker deposits in recesses. The tumbling action during plating provides some deburring of parts and saves you money.

Mechanical Plating & Galvanizing

Along with those post-plating services, we offer chromate finishes in clear trivalent, yellow, black, and olive drab chromates. Mechanical plated arts can be given post plate treatment of dichromate dye for color-coding and phosphate for improved paint adhesion and waxing.

All deposited coatings should have a bright uniform silvery adtm, and a matte to medium-bright luster.

Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. Provide heavy-duty corrosion resistance: Neither will be great for long-term marine exposure, I would suggest a high-build organic coating system probably with a zinc-based b965 or thermal spray base layer. This mechanical plating process characteristically makes this technology an ideal choice for plating hardened steel springs.

Some installations can increase stamping aatm from the same die-sets and eliminate barrel or vibratory finishing steps in deburring.
