Visual erosion examples based on that occurred in the minerals and oil and gas industries are illustrated by a paint modeling technique. The visual paint patterns were used to illustrate erosion damage “hot spots”. This provided an insight into the underlining fluid dynamics process involved with erosion damages. This insight allows design changes to be made to reduce erosion, illustrated by examples...
Organic coatings are the most commonly used system for protection from corrosion. In many applications, the protective properties against corrosion are associated with several other properties, including resistance to abrasion and good aesthetic appearance. This is particularly important for the automotive and transport industry, building trade, domestic products and packaging.The aim of this work...
In the automotive industry, polymer components are routinely employed in a wide variety of situations. Where such components are employed in visible applications, their aesthetic appeal is commonly enhanced by the application of surface coatings, such as paints or chrome plate. However, throughout the lifecycle of the component, coating removal may be required to enhance its ability to be reused or...
Cryogenic blasting is a pneumatic jet based process in which solid carbon dioxide (CO 2 ) particles impinge upon a surface. It may be employed to remove paint layers from a variety of substrate materials. During this process, the substrate material may be damaged due to the carbon dioxide particles striking the substrate surface. For applications where the component is to be recoated, such...
Many of the factors which control the rate of erosion, such as particle velocity, number of particles impacting a surface and their angle of impingement can be largely determined by the flow conditions of the system. In fact, many practical examples may be found when a change in the flow conditions has greatly increased or decreased erosion. In general where the flow direction changes rapidly (turbine...
