The selection of the proper coatings and treatments to be used for a wear resistant job is the most important step in doing the job successfully. Each wear coating has different characteristics of strength, shrinkage, hardness, and other qualities, such that there is a material for every wear resistant category. There are two general material approaches to wear resistance. Firstly, wear resistant material can be used as a material that resists wear by virtue of its composition or its properties. Secondly, as a structural part material that can be used, while its surface is modified by treatments and coatings to ...

Guidelines for Choosing a Metal Parts Cleaning Method

Today, most metal fabricators and machine shops have two parts-cleaning options: aqueous water-based cleaning or solvent-based cleaning inside a vapor degreaser. Both methods can provide quality cleaning results. However, each has its distinct drawbacks and advantages. Aqueous or water cleaning is a process that uses water and chemical additives to get parts clean. The water is treated with detergents or surfactants, builders, emulsifiers, saponifers, sequestering agents, chelating agents and a variety of other compounds to boost the cleaning performance. Using a three-step process, parts are washed in a series of machines, followed by a secondary rinse step to carry away ...

Picking the Correct Pretreatment Before Powder Coating

Q: We make component parts for agricultural equipment. Some of the parts are small brackets and some are very large parts with bolted components, welds and different metal thicknesses. We want to convert from liquid coating to powder coating and we are sorting through the different options for part preparation. At present, we wash all the parts in a three-stage washer and coat them with a baking enamel. We have some problems with rust around the welds and the edges of the parts, and we need to get better in these areas. We expect the powder to hold up better, ...

The nanocoatings holding back corrosion

Corrosion is an age-old problem, but some of the latest solutions are distinctly 21st century. Corrosion has been a problem for as long as human have used metals – it’s no coincidence that the metals we consider most precious are those that do not corrode. Protecting metals that do corrode has involved various surface treatments, from simply painting the surface to current magnesium iron phosphate ceramic coatings for steel. Chemicals that could slow down corrosion, known as corrosion inhibitors, have been widely used in paints since the industrial revolution. But over the past decade, new types of nanostructured protective coatings ...

Abrasion Resistant and Wear Resistant Coatings

Wear or abrasion resistant coatings have loads of applications, particularly in industrial production. These coatings are significantly more durable than regular ones because of their excellent ability to resist wear and tear. Whether it is high traffic roads, assets made from heavy metal, machines or anything similar, applying impact resistant paint can prolong your asset’s life. Some equipment requires regular upkeep to remain in excellent working condition. However, their exposure to a variety of elements impacts their overall quality, resulting in replacement, breakdown or even costly repairs. Things like these can be a massive problem in terms of depreciation costs, ...

Choosing a Metal-Forming Lubricant

I recently came across an oil called ISOFORM 900 in the metal-forming process. Can you describe its physical properties and its equivalent use?" ISOFORM 900 is a product from Petrofer that is designed for cold-forming fluids, specifically those of steel, stainless steel, aluminum, titanium and copper-based alloys. Metal-forming processes have been around for thousands of years. Today's varieties in the metal-forming industries include complex processes such as sheet metal-stamping, wire-drawing, hydroforming, rolling and hot- or cold-forming. These processes often have high pressures between acting surfaces and in many applications high temperatures as well. Within each of these processes, several techniques ...
