Most commonly used plating. High density of plate affords excellent corrosion resistance. TYPE I coating is very susceptible to stains and fingerprints. TYPE II coating is excellent for resistance to moisture and humidity, and a paint base. Chromate colors besides gold are clear, olive drab and a black treatment. TYPE III is a good paint base. Stress relief is required on metal with a hardness of Rockwell C34 or above and hydrogen embrittlement relief is required after plating on metal with a hardness of Rockwell C36 or above. |

It is generally agreed by most authorities that this treatment is the best all around coating for magnesium in existence. The coating thickness is approximately 40 percent penetration and 60 percent buildup. When selected organic post-treatments are applied, a salt spray test of up to 1000 hours is possible. The coating is non-conductive. TYPE II coatings have extremely good resistance to abrasion. TYPE I light coatings are normally tan in color. TYPE II heavy coatings will range from an oatmeal color to dark brown, depending on the thickness of the coating. HAE coatings are not affected by extreme temperature variations. A heavy coated panel heated to 1075 degrees F. and plunged into ice water will show no ill effects to the coating. This process can be selectively applied by masking the areas that have to be free of coating for: electrical grounding, close tolerance dimensions, heavy buildups for salvage purposes, etc. The coating may be used on all magnesium alloys. |

No dimensional change Salt spray is considered a “destructive” test. | These tests are designed to verify the integrity of various metals and metal surface finishes. The salt spray method is used extensively for testing of anodize, chemical films, and plated metal coatings. The salt spray, humidity, water immersion, and copper sulfate methods are used to check on the passivity of stainless steel after the passivation process. |

Dull ( matte) or bright appearance must be specified. Underplate of copper (.0001 min.) or nickel (.000050 min.) must be used on brass and zinc alloys to prevent zinc migration. For CLASS A plating that will not be exposed to solder temperatures (especially those that must function as electrically conductive surfaces), a nickel underplate of .000050 min., shall be applied prior to tin plating. Dull and bright tin have excellent solderability and fair corrosion resistance. At room temperature dull (matte) plating oxidizes slowly but bright plating oxidizes less readily. Dull and bright tin have low electrical resistance and antigalling properties. |

Gives galvanic protection to base metal. Untreated (TYPE I) zinc plating does not maintain its bright surface for a very long period of time. TYPE II AND TYPE III treatments retard the formation of white corrosion products on the plated surface. The service life of zinc plating is a function of conditions such as thickness, exposure, and usage. The Service Conditions are as follows SC 4 – Very Severe. Exposure to harsh conditions, or subject to frequent exposure to moisture, cleaners, and saline solutions, and damage by denting, scratching, or abrasive wear. SC 3 – Severe: Exposure to condensation, perspiration, infrequent wetting by rain, and cleaners. SC 2 – Moderate: Exposure mostly to dry indoor atmospheres but subject to occasional condensation, wear, or abrasion. SC 1 – Mild: Exposure to indoor atmospheres with rare condensation and subject to minimum wear or abrasion. |
