Less wear thanks to lower friction with coatings

There is so much you can achieve with coated surfaces. They add value to products, making them more competitive. Through a series of cases based on the needs of different sectors, Sirris will give you an idea about their potential. The second blog discusses how coating can help to cope with wear of components in the manufacturing industry.

Many products derive a large part of their functional properties from how their surfaces interact with the surroundings. What these properties are differs between sectors. Manufacturing companies produce all kinds of components, ranging from consumer goods to machines and cars, which are subject to wear due to friction. To deal with this friction, the friction coefficient can be customised by means of textures or reduced by means of coatings. After a first blog about textures we will now discuss the options with coatings.

Wide applicability

Coatings are a proven method to create low friction in applications in the manufacturing industry and to prevent rapid wear and tear. In addition, the process conditions can also be improved or it is possible to work without or with less liquid lubricants. This leads directly to savings in lubricants and environmental costs. In other applications, the use of liquid lubricants is not even possible. Think of production machines developed for the medical and food industry. Or those in which a closed design makes it impossible to provide regular lubrication.

Due to its wide applicability and high added value, many coatings have been developed over the years to reduce friction. However, the large choice of coatings makes it difficult for companies to know which coating will produce the best results in their specific process or product. After all, this is determined by a whole series of factors: the operating environment (e.g. temperature, humidity), the type of wear (e.g. abrasive, adhesive, erosive), the process parameters (e.g. load, speed, frequency) and the composition of the substrate (e.g. hardness, yield strength) determine to a large extent which coating will provide the highest added value to the product or process.

In the casebook on functional surfaces that we are composing for you, we give a number of examples of coatings and their applicability, and we also show how the combination of coatings and textures can contribute to lower friction and wear. 

In a next blog we will have a look at the use of textures and coatings in the food industry. Would you like to stay up-to-date with our series about functional surfaces? Register here
