Shot blasting as a mechanical surface preparation process is widely used in finishing metallic parts. Sophistication in the use of this technique could range from simple manual systems to computer-controlled equipment for preparing aerospace and automotive components. It’s important to grasp the basics of blast cleaning to appreciate sources of savings in operating costs. Selecting the right machine and degree of automation is also important in achieving the final goal. Over the years, repeatability of finish, consistency of results, and operating costs have gained importance among blast equipment users. This has led to identification of critical process parameters that have tangible impact on the final result. Process variables such as media size, velocity, shape and flow rate, all play their own critical roles in determining the end result of your operation. Such parameters are not monitored in a conventional cleaning process. However, in an allied process called shot peening, such parameters have to be kept in close check. Therefore, lessons learnt from peening leads us in an evolutionary path in the blast cleaning. Monitoring and adjusting process parameters such as the impact energy, media size can result in a more controlled cleaning operation resulting in operating cost savings. The shot blasting industry, albeit at a slower pace, has embraced technology over the past ten years. But there’s more to come in terms of brand-new applications, materials, designs and techniques. Our discussion will conclude with information on what to expect from this industry going forward.

Viscous Elastic Coatings easily overcome many of the common issues that cause traditional coating to fail. Viscous elastic coatings offer immediate adhesion without the need for primer, require minimal surface preparation and form a homologue, continuous, self-healing protective layer.

This presentation will outline the results and conclusions of a number of years of testing and experience in surface preparation for high-performance coatings. Testing has shown that there are a number of important surface preparation variables that are not routinely monitored and controlled on coating projects. These variables will be identified and guidance will be provided on appropriate treatment to achieve coating results.
