Agricultural engines technology

Harvester

Harvesting and processing of corn and grain puts an enormous strain on the tools of modern agricultural harvester.

In comparison to nitriding, hard chromium and thermal spray coatings the durabilty of harvesters  has increased by more than 60 %. The combination of case-hardened and heat-treatable steel with Borocoat®-diffusion coatings withstand chippings caused by percussive strains from solid substances such as sand, stones and plant remains.

As a work environment, nature is an extremely unpredictable force that poses many
challanges. Harvesting and processing of corn and grain puts an enormous strain on
the tools of modern agricultural harvester. The question of how to prevent wear is one
that agricultural engineers are struggling to find an answer to. BorTec has found a
way to balance stress and wear resistance in agricultural engine technology.

Wear protection for harvesting machines

Harvesting machines are most affected by abrasive wear and surface spalling. The constant work near the ground causes sand and small rocks to be carried over. As a result, they collide with the chaffs and shredding machines, wearing them off considerably. Chaffs and shredding machines are particularly important in regards to processing plants. If worn out, they lose much of their efficiency and performance
quality, causing plant fibers to be cut wrong. Agriculturalists are familiar with the difficulty of exchanging wearing parts for harvesting machines such as combine harvesters, forage harvesters, potato diggers, and beet harvesters. The removal of the
old parts and the flawless installation of the wearing parts is not only expensive but also time-consuming. Time and money that most agriculturists do not have.

Bortec- Service for better wear protection in agricultural engine technology

BorTec offers a solution with the BoroCoat diffusion layers. It is an effective long term solution that protects agricultural engine components against wear. Therefore, profitability can be greatly improved. In comparison to nitriding, hard chromium and
thermal spray coatings, the durabilty of harvesters has increased by more than 100 % using BoroCoat® diffusion layers. The combination of case-hardened and heat-treatable steel with Borocoat®-diffusion coatings withstand chippings caused by percussive strains from solid substances such as sand, stones and plant remains.

Borocoat®-diffusion layers protect harvesting machines against:

  • extreme abrasive wear
  • surface spalling
