Magnetic Particle Inspection
This inspection method is used for detecting cracks, seams, laps, inclusions, welding flaws, and discontinuities on the surface of ferromagnetic materials.

Liquid Penetrant Inspection
This inspection method is generally used on aluminum, magnesium, and stainless steel. It can, however, be useful on other metals and materials. Detects cracks, discontinuities, corrosion, welding flaws, laps, cold shuts, and porosity
Dissolves all traces of foreign materials such as pieces of iron particles, tool scrapings, chips, etc. that will cause rust or stain spots if they are not removed. A thin transparent passive film forms over the surface and prevents this condition from occurring. The presence of rust and/or heavy heat treat scale may necessitate a pre-pickle . Our inspection personnel conduct the required copper sulfate test, salt spray and water immersion inspection test in accordace with AMS-STD-753 and ASTM B117

Sulfuric acid anodizing: Not to be applied to assemblies or parts with joints, or recesses which might entrap solution. Good electrical barrier and paint base. May be dyed in all colors. Dichromate seal, when specified, will impart yellow color. Produces excellent decorative finishes when the part is either polished, brushed, or bright dipped prior to anodizing, good corrotion and abrasion resistance.
+Cadmium Plating
The most commonly used plating. High density of plate affords excellent corrosion resistance.
Type I coating is very susceptible of 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 black treatment.
Type III is a good paint base.
Stress relieve is required on metal with a hardness of Rockwell C34 or above and hydrogen embrittlement reliefis required after plating on metal with a hardness of Rockwell C36 or above
This process is a electrolytic removal of metal in a highly ionic solution by means of an electrical potential and current, or in other worlds, reverse electroplating.
