What is BS EN 15042-1- Thickness of thin films about?
BS EN 15042-1 is the first part of the multi-series International Standard that covers thickness measurement of coatings and characterization of surfaces with surface waves.
BS EN 15042-1 gives guidance on methods of determining the elastic constants, density, and thickness of thin films by laser-induced surface acoustic waves. BS EN 15042-1 defines terms and describes procedures.
Who is BS EN 15042-1- Thickness of thin films for?
BS EN 15042-1 on determining elastic constants, density, and thickness of films by laser-induced surface acoustic waves is relevant to:
- Manufacturers of measuring equipment
- Ultrasonic and material testing authorities
- Coating thickness measurement personnel
- Magnetic engineers
- Electro-mechanical engineers
Why should you use BS EN 15042-1- Thickness of thin films?
Surface acoustic waves are ultrasonic waves propagating along the surface of the material. For hard coatings, Young's modulus correlates with a hardness that can be measured only with increasing error for reducing film thickness. Measuring the film modulus is a method for controlling the film quality and monitoring the technological process.
BS EN 15042-1 describes the elastic modulus (Young's modulus) of the film, which helps you determine the mechanical behavior of the coated material, the development of residual stresses, and the mechanical energy induced by externally loading the coated surface.
BS EN 15042-1 informs you about the elastic constants, density, and thickness of thin films by laser-induced surface acoustic waves, which helps you acknowledge its influence on the creation and growth of cracks in the film and, therefore, influencing the failure behaviour of the coated material.
BS EN 15042-1 also talks about other several static and dynamic techniques used to measure Young's modulus of the film and provides an overview of the principles of these alternatives.
BS EN 15042-1 describes the laser-acoustic technique which is a practicable method for reproducibly determining Young's modulus of films with thickness down to less than 10 nm without special sample preparation. The technique also enables the film thickness to be measured and provides access to the film density.
Overall, BS EN 15042-1 is useful as helps in determining elastic constants, density, and thickness of films by laser-induced surface acoustic waves, which can be helpful for your business.
