WebCoating and film testing. Driven by emerging technology and to suit customer special requirements Sigma ‘s comprehensive range of bond tests is always increasing. One of our latest applications made scratch testing of complex coating much easier to achieve and increased throughput by several orders of magnitude. WebEddy current testing and more recently eddy current array (ECA) is one of the standards of thickness measurement because it can be used for nonconductive coatings on conductive-base materials. By inducing a magnetic field, ECA can read the currents to create a picture of the surface. This helps detect any abrasions.
