All deposited coatings should have a bright uniform silvery appearance, and a matte to medium-bright luster. The zinc coatings are classified according to thickness and identified into two types; as coated without supplementary treatments or with colored chromate conversion treatment.

ASTM B695-04

This abstract is a brief summary of the referenced standard. Custom Industrial Processing, Inc. Work Item s – proposed revisions of this standard.

Electroplating Mechanical Galvanizing vs. The mechanical plating process is a process in which fine metal powders are cold welded to metal components without electricity and without heat. 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.

Mechanical Plating & Galvanizing

All tests results should comply with the given requirements. The main advantage of mechanical plating over electroplating is the elimination of hydrogen embrittlement.

CIP is certified to work with coating for zinc deposited mechanically onto iron and steel basis metals. Hot Dip Galvanizing Resin Impregnation. Once the plating reaches the desired thickness the parts are then dried and post-plating finishes are applied if required. What is Hydrogen Embrittlement Hydrogen embrittlement is a phenomenon which causes materials to lose their strength and become brittle.

CIP offers two post-plating services: The inch-pound b965 of SI units are given for informational purposes. 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.

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. Nonmagnetic Coatings on Magnetic Basis Metals. The mechanical plating process takes place in a tumbling barrel filled with tumbling media e.

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

Electroplating The main advantage of mechanical plating over electroplating is the elimination of hydrogen embrittlement. Samples asm be tested for adhesion, salt-spray corrosion resistance, appearance, thickness, and absence 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. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. The thickest coating classes are usually referred to as “mechanically galvanized”.

Mechanical plating takes place at room temperature and does not induce hydrogen embrittlement of which hardened steels asfm highly susceptible. This specification covers the requirements for zinc coatings that are mechanically deposited on iron or steel basis metals.
