CIP is certified to work with coating for zinc deposited mechanically onto iron and steel basis metals. The main advantage of mechanical plating over electroplating is the elimination of hydrogen embrittlement.
We also work with both Type I as coated, without supplementary treatment and Type II with chromate conversion treatment B specifications for special processing needs. Mechanical plating takes place at room temperature and does not induce hydrogen embrittlement of which hardened steels are highly susceptible. 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.
ASTM B – 04 Standard Specification for Coatings of Zinc Mechanically Deposited on Iron and Steel
Once the plating reaches the desired thickness the parts are then dried and post-plating finishes are applied if required. Hot Dip Galvanizing Resin Impregnation. Custom Industrial Processing, Inc. Any metal that can be made into a fine powder can be mechanically plated, however CIP specializes in zinc, tin, and aluminum. Uniformity of thickness depends on part size and shape with typically thinner deposits on edges and thicker deposits in recesses.
Specializing in Mechanical Zinc Plating and Galvanizing Uniformity of thickness depends on part size and shape with typically thinner deposits on edges and thicker deposits in recesses. This specification covers the requirements for zinc coatings that are mechanically deposited on iron or steel basis metals. Hydrogen embrittlement is a phenomenon which causes materials to lose their strength and become brittle. Samples should be tested for adhesion, salt-spray corrosion resistance, appearance, thickness, and absence of hydrogen embrittlement.
What is Hydrogen Asmt Hydrogen embrittlement is a phenomenon which causes materials to lose their strength and become brittle. The thickest coating classes are usually referred h695 as “mechanically galvanized”.
The ashm coatings are classified according to thickness and identified into two types; as coated without supplementary treatments or with colored wstm conversion treatment. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
CIP offers two post-plating services: Click here for a quote or call us at The mechanical plating process takes place in a tumbling barrel filled with tumbling media e. Historical Version s – view previous versions of standard. Nonmagnetic Coatings on Magnetic Basis Metals. All tests results should comply with the given requirements. All deposited coatings should have a bright uniform silvery appearance, and a matte to medium-bright luster.
This abstract is a brief summary of the referenced standard.
Link to Active This link will always route to the current Active version of the standard. The mechanical plating process is a process in which fine metal powders are cold welded to metal components without electricity and without heat. 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.
Along with those post-plating services, we offer chromate finishes in clear trivalent, yellow, black, and olive drab chromates.
The inch-pound equivalents of SI units are given for informational purposes. It is the wstm of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
