R&D P2020 Project

Research and technological development project named “WEAR – A solution for critical production equipment in the food and pharmaceutical industries”.

With an overall investment amount of over 450 thousand euros, the “WEAR” project was financed by PORTUGAL 2020 under the regional operational program NORTE 2020, in the amount of 325,256.48 euros, from the European Regional Development Fund (FEDER).

Project objectives

The WEAR project investigates the wear behaviour of metallic materials with modified surface, aiming its application in the development of technology supporting a new generation of equipment for solid bulks handling, intended to be incorporated in the production lines of the agriculture, food and pharmaceutical industries.

With this new generation of more robust and efficient equipment, it is intended to reduce the risk of incidents, downtime and the need for corrective interventions, while contributing to greater quality and safety in processed products.


Parts (blades) manufactured with three different types of stainless steel were used: AISI 304L, AISI 316L and AISI420.

Several types of coatings were tested: DLC, TiB2, TiAlCrN and TiAlCN PVD. The nitriding of the parts was also evaluated. The blades were tested on prototype mixers, of different scales, manufactured for this particular project. To speed up the wear process, sand was used as the material to be mixed.

The tests were performed with blade rotation speed close to 1500 rpm, for variable operating periods.

After the tests, the loss of mass and the topography of the surface of the blades caused by the wear action were analysed.
