Coating PENETRATES base metal as much as builds up on the surface. The term THICKNESS includes both the buildup and penetration. . Type III Anodize Thickness Guide. Alloy. Major Constituent(in) Maximum Thickness* Color Overtones*** 1100. 99.5% pure Alum..003. Gray/Green** 2011. Copper. Not .For Type I and Type II anodize, the rule of thumb we use at Anoplate is 1/3 buildup and 2/3 penetration. Since Type I, i.e. chromic or other thin anodize coatings, have limited overall thickness, the buildup is typically under 0.0001 inch per surface so little if any adjustment is necessary to accommodate the overall dimensional change.
The above publication goes on to call out the designations of other more specific coatings and methods of pretreatment of the aluminum prior to anodizing. Coating thickness can be measured by an "eddy current," nondestructive test instrument as per ASTM B 244-79, or by cutting a cross-section of the anodized aluminum, mounting it in a slide .Measuring Anodizing Thickness on Aluminum. How to Measure Powder Coating Thickness on Steel, Aluminum, or Wood. Coating Thickness Gages . fully electronic PosiTector 6000 Coating Thickness Gage uses magnetic and eddy current principles to measure coating thickness on both ferrous and non-ferrous metals, accurately and quickly.

A coating thickness gauge is an essential quality assurance tool when anodizing, galvanizing and applying zinc coating to metallic surfaces. A coating thickness gauge also is used to measure body paint thickness and uniformity on pre-owned cars, revealing repainted spots, identifying hidden damages and exposing undisclosed accidents .Coatings of moderate thickness 1.8 μm to 25 μm (0.00007" to 0.001") [16] are known as Type II in North America, as named by MIL-A-8625, while coatings thicker than 25 μm (0.001") are known as Type III, hard-coat, hard anodizing, or engineered anodizing. Very thin coatings similar to those produced by chromic anodizing are known as Type IIB.
The thinnest coatings are usually seen in clear anodizing, since anodizing dyes require at least .0004″- .0006″ of coating thickness to dye properly. With an average coating thickness of .0008″, the build-up will typically be .0002″-.0003″, which is small enough that it can be effectively ignored in most machined and fabricated parts.

Specially for the thickness measurement of coating on small workpiece.The nominal coating thickness is not all build-up on the original surface and calculating the effect of anodising on a part's dimensions requires some understanding of how anodising grows. . The SI unit of measurement used for coating thickness in the majority of standards, throughout our website and on any documentation we produce, is the . Accurate coating thickness measurement enables plating, anodizing, powder coating, and other coatings, preventing corrosion or wear of metal substrates. The following reviews the industry’s challenges, along with the benefits of instantaneous handheld coating thickness gages.
Coating Thickness Measurement: Methods such as eddy current testing and cross-sectional microscopy are used. . The effect depends on the anodizing type and coating thickness, with thicker coatings generally reducing fatigue strength. 5.2 Hardness and Wear Resistance. Hard anodizing (Type III) significantly increases the hardness and wear .DeFelsko manufactures a hand-held, non-destructive coating thickness gage that is ideal for measuring the thickness of anodizing on aluminum. Measurement Challenges To efficiently control the thickness of the thin coatings of an anodizing process, an accurate non-destructive means of measurement is required.Coating thickness is an important attribute of every type of anodized finish. It may be specified as either coating thickness or coating weight, or both. Common units of measurement are: inches, mils, microns, where 1.0 mil equals 0.001 inch (one mil = one one-thousandth of an inch); 25 microns equals 1.0 mil; or 1 micron equals 0.00004 inches. Eddy current coating thickness gages (e.g. PosiTector 6000 N Series) look and operate like electronic magnetic gages. They are used to measure paint and coating thickness over all nonferrous metals.

A permanent magnet is mounted on a balanced arm and the force required to pull this magnet from the surface of the coating is a measure of the thickness of the coating. Force is applied through a helical spring attached to the balanced arm at one end and to a scale wheel at the other.
Significance and Use 5.1 The thickness of a coating is often critical to its performance. This eddy-current method is nondestructive and is suitable for measuring the thickness of anodic coatings on aluminum, as well as the thickness of most nonconductiveDry film thickness measurement is necessarily required. Coating thickness gauges offered can be used on all metal types including non-magnetic coatings such as paint, enamel, chrome on ferrous substrates such as steel . In addition, non-conductive coatings such as paint and anodizing coatings on non-ferrous substrates. On the other hand an added thickness of coating by anodic oxidation might be essential for extreme robustness and wear resistance required in certain applications like heavy machinery parts. . ASM International – “Alodine vs. Anodize Coatings for Aluminum: Properties and Applications” . Figure 4: Schematic diagram of a probe utilising the magnetic induction method to measure the thickness of a coating on a ferromagnetic substrate. The thickness of the coating dictates the current and subsequent magnetic field generated.
