The salt spray test (or salt fog test) is a standardized and popular corrosion test method, used to check corrosion resistance of materials and surface coatings.Usually, the materials to be tested are metallic (although stone, ceramics, and polymers may also be tested) and finished with a surface coating which is intended to provide a degree of corrosion protection to the underlying metal.
Mangalloy is a unique non-magnetic steel with extreme anti-wear properties. The material is very resistant to abrasion and will achieve up to three times its surface hardness during conditions of impact, without any increase in brittleness which is usually associated with hardness. [2] This allows mangalloy to retain its toughness.
When a test fails to meet the thickness and other test requirements that are in place to ensure plane strain conditions, the fracture toughness value produced is given the designation . Fracture toughness is a quantitative way of expressing a material's resistance to crack propagation and standard values for a given material are generally ...
The Izod impact strength test is an ASTM standard method of determining the impact resistance of materials. A pivoting arm is raised to a specific height (constant potential energy) and then released. The arm swings down hitting a notched sample, breaking the specimen. The energy absorbed by the sample is calculated from the height the arm ...
Metallurgical failure analysis is the process to determine the mechanism that has caused a metal component to fail.It can identify the cause of failure, providing insight into the root cause and potential solutions to prevent similar failures in the future, as well as culpability, which is important in legal cases.

Increases corrosion resistance Copper: 0.1–0.4 Corrosion resistance Lead — Improved machinability Manganese: 0.25–0.40 Combines with sulfur and with phosphorus to reduce brittleness. Also helps to remove excess oxygen. >1 Increases hardenability by lowering transformation points and causing transformations to be sluggish Molybdenum: 0.2–5
The Kesternich test is a common name for the corrosion test with sulfur dioxide (SO 2) under general moisture condensation. This test was developed in 1951 by Wilhelm Kesternich [1] to simulate the damaging effects of acid rain. Acid rain and acidic industrial pollutants are corrosive and can degrade coatings and plated surfaces. Kesternich ...
In materials science, the Charpy impact test, also known as the Charpy V-notch test, is a standardized high strain rate test which determines the amount of energy absorbed by a material during fracture. Absorbed energy is a measure of the material's notch toughness. It is widely used in industry, since it is easy to prepare and conduct and ...
