A piece of equipment can deteriorate rapidly even after it has just been replaced or while using a material with high hardness. The cause does not lie only in the material itself but also depends on the actual operating conditions at the surface<\/strong>.<\/p>\n

Material flow, particle size, impact, temperature, moisture, and the chemical environment can all change the way equipment deteriorates. Even two locations close to each other on the same production line may be subjected to different mechanisms.<\/p>\n

Therefore, before selecting a material group, three issues need to be identified: which mechanism is causing the damage at the location, what the operating conditions are at that location, and to what extent the damage is affecting the equipment or production line<\/strong>.<\/p>\n

This article provides an overview of GAC’s approach to material wear mechanisms. The content on damage-pattern identification, the effects of temperature, material build-up, common wear locations, and operational consequences is divided into 7 in-depth articles in the following sections.<\/p>\n

1. \u201cWear\u201d does not involve only one mechanism<\/span><\/h2>\n

Many forms of surface damage in industrial plants are commonly grouped under the general term \u201cwear.\u201d However, materials can deteriorate through different mechanisms.<\/p>\n

Within this content system, wear is divided into four main groups: mechanical wear, adhesive wear, chemical wear, and fatigue wear<\/strong>. These mechanisms may occur individually or simultaneously at the same location.<\/p>\n

Mechanical wear can also occur under different forms of action such as scratching, crushing, or particle-laden flow. Impact and erosion are not separated into independent types of wear but are considered in relation to the mechanism occurring at the surface.<\/p>\n

Correctly distinguishing the mechanism from the outset helps avoid situations in which a location is damaged by one mechanism while the solution is selected based on properties suited to another mechanism.<\/p>\n

You can learn more about how to distinguish each wear type, the different forms of mechanical wear, and the signs they leave on the surface in Part 1: 4 types of wear and their identifying signs on the surface<\/strong><\/a><\/span>.<\/p>\n

2. Surface damage patterns provide clues for narrowing down the mechanism<\/span><\/h2>\n

The technical team conducts a visual inspection of the equipment surface at the site to correctly identify the wear mechanism before selecting the material<\/figcaption><\/figure>\n

Each mechanism usually leaves different signs on the surface. Therefore, observing the damage pattern is one of the first steps engineers use to identify the group of causes requiring further investigation<\/strong>.<\/p>\n

However, damage patterns should not be interpreted separately from operating conditions. Material-flow direction, temperature, particle size, moisture, impact location, and repair history can all change the way the surface deteriorates.<\/p>\n

Another important point is that not every visible phenomenon on the equipment belongs to a wear mechanism. Two cases that are commonly confused are:<\/p>\n
