Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. All tests results should comply with the given requirements. What is Hydrogen Embrittlement Hydrogen embrittlement h695 a phenomenon which causes materials to lose their strength and become brittle.
Nonmagnetic Coatings on Magnetic Basis Metals. Hot Dip Galvanizing Resin Impregnation. The main advantage of mechanical plating over electroplating is the elimination of hydrogen embrittlement. Historical Version s – view previous versions of standard.
Hydrogen embrittlement is a phenomenon which causes materials to lose their strength and become brittle. Electroplating Mechanical Galvanizing vs. CIP offers two post-plating services: Click here for a quote or call us at Once the plating reaches the desired thickness the parts are then dried and post-plating finishes are applied if required. Along with those asym services, we offer chromate finishes in clear trivalent, yellow, black, and olive drab chromates.
Mechanical plating takes place at room temperature and does not induce hydrogen embrittlement of which hardened steels are highly susceptible. 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.
ASTM B – 04 Standard Specification for Coatings of Zinc Mechanically Deposited on Iron and Steel
Samples should be tested for adhesion, salt-spray corrosion resistance, appearance, thickness, and absence of hydrogen embrittlement. Electroplating The main advantage of mechanical plating over electroplating is the elimination of hydrogen embrittlement. All deposited coatings should have a bright uniform silvery appearance, and a matte to medium-bright luster. Work Item s aetm proposed revisions of this standard.

The mechanical plating process takes place in n695 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. The thickest coating classes are usually b6695 to as “mechanically galvanized”.

Uniformity of thickness depends on part size and shape with typically thinner deposits on edges and thicker deposits in recesses. The zinc coatings are classified according to thickness and identified into two types; as coated without supplementary treatments or with colored chromate conversion treatment.

The inch-pound equivalents of SI units are given for informational purposes. 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. Any metal that can be made into a fine powder can be mechanically plated, however CIP specializes in zinc, tin, and aluminum.

It is the ast of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
The mechanical plating process is a process in which fine metal powders are cold welded to metal components without electricity and without heat. CIP is certified to work with coating for zinc deposited mechanically onto iron and steel basis metals.
