What Is Eddy Current Testing?

Eddy current testing is a method of non-destructive testing, or NDT, that utilizes the process of electromagnetic induction for the evaluation and measurement of conductive materials without causing damage. Eddy current testing, or ECT, is used primarily in the detection of surface and sub-surface flaws such as cracks in conductive materials like metal, and it […]

What Is Electrocleaning?

You may be quite familiar with electroplating and all the benefits this plating method offers. However, most people don’t know exactly what goes into the electroplating process, especially the early steps. One of the first steps of the electroplating process, in fact, is preparing the surface. This process of preparation is used as a way […]

What Causes Electroplated Coatings to Flake or Peel?

Poor adhesion is a common problem that can negatively impact the performance and longevity of an electroplated coating. Improper adhesion often takes the form of flaking, which occurs when the coating lifts, separates and peels away from the surface of the substrate. This results in large, bare or nearly bare areas that are no longer […]

Types of Corrosion Testing for Plated Parts and Components

Rust can wreak havoc on metal, so corrosion testing is a common practice for most companies that are heavy users of metal in their manufacturing processes. Over the years, a number of testing protocols have been developed, including cyclic corrosion testing, salt spray testing, humidity testing, Kesternich chamber testing and specialized tests that accurately mimic […]

Benefits of Gold-Plated Electrical Contacts

Electrical contacts are those crucial electrical circuit components for controlling the flow of electricity. Typically found in circuit breakers, switches and relays, contacts are made of electrically conductive metal. When two contacts touch, the circuit closes. Conversely, when the contacts are separated by an insulating gap, it interrupts — or opens — the circuit. In […]

How to Avoid Tarnishing

While metal finishing processes such as electroplating and electroless plating provide numerous benefits, the presence of post-plate tarnishing can diminish the value of the plating process over time. Tarnish is essentially a thin layer of corrosion that frequently develops on the surface of a part in the form of a dull blackish or grayish film. […]

Alternatives to Cadmium for Plating Connectors

Before the 1960s, cadmium, also referred to by its elemental abbreviation “Cd,” was the go-to material for numerous industries. The blossoming aerospace industry and rapidly expanding military industry both sought cadmium for use in several key mechanical applications, but things changed when expanding research discovered several drawbacks of the material, both to public health and […]
