Mechanical characterization of corrosion-resistant coatings

Bruker Nano Surfaces and Metrology
23 Jul 2023

Corrosion-resistant coatings play a crucial role in the process of food preservation. Soft drinks, which are highly acidic, are a specific example of food products that require corrosion-resistant coatings. These films must retain their functional integrity when exposed to various physical and chemical stresses. Two important attributes are the mechanical strength and the film adhesion, which are functions of the curing process. In this application note Bruker Nano discusses how the Hysitron® TS 77 Select, automated benchtop nanomechanical and nanotribological test instrument can be used to characterize food and beverage can liner coatings.

NanotechnologyNanotechnology, or nanotech, is an engineering technique using molecular scale functional systems. Applications of nanotechnology include medicine and medical devices, electronics, air and water purification, food science and energy production.Mechanical TestingMechanical testing explores the elastic and inelastic nature of a material when force is applied. A mechanical test shows whether a material is suitable for its intended application by measuring hardness, tensile strength, elongation, elasticity, and fatigue limit.Non-Destructive TechniquesNon-destructive techniques (NDT) describes a variety of analytical techniques used to evaluate the properties of a material. Common methods include ultrasonic, magnetic-particle, liquid penetrant, radiographic, remote visual inspection (RVI), and eddy-current testing. NDT is regularly used in forensic engineering, civil engineering, mechanical engineering, electrical engineering, systems engineering, aeronautical engineering, and medicine.ProfilometersProfilometers are instruments used to measure a surface's profile, in order to quantify etch depth, deposited film thickness, and surface roughness. They operate in either contact or non-contact modes and may use optical or stylus techniques to make the actual measurements.Light MicroscopyLight microscopes or optical microscopes are used to visualize microscale objects under magnification, including cells, clinical specimens and materials. Lab equipment for light microscopy includes confocal microscopes, fluorescence microscopes, zoom and stereo microscopes. Microscope slides and imaging reagents are available for visualizing samples, as well as various microscope stages and incubators for large or temperature-sensitive samples. Find the best light microscopes in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Atomic Force Microscopy / Scanning Tunneling MicroscopyAtomic force microscopes (AFM) and scanning tunneling microscopes (STM) are high-resolution forms of scanning probe microscope (SPM) used to generate topological information of a sample down to the atomic scale. Instruments can generate an image of the surface topology, manipulate objects and reveal information on localized properties such as Young’s modulus, conductivity, and magnetism. High-quality STM and AFM probes optimized for your application are available, as well as other SPM-based instruments such as scanning ion conductance microscopes (SICM) & near-field scanning optical microscopes (NSOM). Find the best AFM and STM equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Food SafetyFood safety describes the prevention of food-borne illnesses. Contamination with a variety of pathogens can be prevented with adequate temperature control, hygiene and labeling. Food samples can be tested using GC/MS, HPLC, SPE, and qPCR to ensure their adherence to regulations.Quality TestingQuality testing ensures that products meet required specifications and safety standards in various industries, including pharmaceuticals, food, and materials. It is essential for maintaining product quality and consumer safety. Explore quality testing tools in our peer-reviewed product directory; compare products, check reviews, and get pricing directly from manufacturers.
