An investigation was performed to determine the cause of coating failures on several large hinged steel boxes. These boxes were constructed of sheet steel and were allegedly coated with corrosion-resistant coatings. However, after exposure outdoors, much of the paint delaminated and severe corrosion occurred. 22 January 2010
Metal finishing barrel operations are used most often for “bulk” finishing of large quantities of parts. They are the most efficient method for finishing bulk parts and any pieces that do not require individual handling. A hoist system is generally used to transfer the loaded metal finishing barrel assemblies from one process station to the next. 16 December 2009
During the 20th century cheap and abundant energy made corrosion a manageable problem. This era is coming to an end. Soon, industry will find there is less funding available for corrosion prevention after adjusting for rising energy costs. At this time, management will be forced to decide whether to continue with traditional corrosion control practices or change to something new with a greater potential for energy savings. For many, this will be an extremely difficult decision to make. 13 October 2009
The process reliability of pretreatment methods is the basis for high-quality products in the production of metal parts with special surface requirements. The cleaning process is the essential step between the finished shape forming and subsequent surface treatment and surface coating, respectively. Deficiently cleaned parts cause defects in the surface quality of products, leading to high costs due to consequential damages. The proper maintenance of defined concentrations of components, surfactants, and builder ensures optimal results in aqueous cleaning processes. 23 September 2009
The use of fluorescent materials to provide a non-destructive method for on-line inspection has been an area of increased importance to the coatings industry. Significant improvements in productivity have been realized by employing ultraviolet, UV, light curing to produce conformal coatings for computer boards. 31 August 2009
The beta backscatter method of measuring plating and coating thickness was originally introduced nearly 40 years ago. Nearly everyone who has been associated with electronics or metal finishing for any length of time is most likely familiar with this technology, as the use of beta backscatter systems has been extensive within these industries. 30 October 2008
Although 70% of the Earth’s surface is covered in water, nearly all of it is contaminated with salt and therefore inappropriate for most uses. 30 November 2004
It is one of the most common causes of system upsets. To prevent it can take as little as one hour of maintenance labor per month and an investment as modest as a hundred dollars. But the cause of this problem, which can cost you many hours of aggravation and many dollars in fines, is rarely the first thing the busy plater thinks of when it first rears its ugly head. It is pH probe maintenance. 01 May 2004
