Solutions to problems of wear and friction.
Built from the Greek roots Tribo ( “rubbing”) and loggia ( “beginning”, “study”), tribology is the science that studies the phenomena resulting from the interaction of surfaces in relative motion.
This science covers all areas of friction, wear and lubrication, which can be defined as follows:
- Friction phenomenon that tends to oppose the movement of a surface in contact with another.
- Wear: Degradation of a surface resulting in a change in the geometry, mass loss, etc. Several types of wear on the tribology focuses:
- Abrasion – Erosion
- Surface fatigue
- The tribo-corrosion
- Lubrication Techniques to reduce friction and wear between two elements in contact and moving relative to each other.
These phenomena include a multitude of parameters that significantly influence the operation of the system, such as movement characteristics (amplitude, speed, etc.), contact geometry (open / closed, tolerances), external stresses (pressure, number cycles) through the environment (temperature, humidity), the topography of the pieces (roughness) and the combination of the material involved (mechanical characteristics, composition).
These tribological studies by the widespread use of treatments and surface coatings allow optimization of the surfaces in order to ensure the proper functioning and reliability of the machines, reducing the cost of obtaining surfaces with good friction, improvement performance and durability of machines allowing ensure the safety of goods and persons.
Treatments and surface coatings (TRD’s) play a recognized unanimously in solving tribological problems fundamental role.
Whether treatment by structural transformation (induction hardening), diffusion (ARCOR, TENIFER, SURSULF, STANAL), conversion (PHOSPHATE, SULF BT), by coating (TEGLISS, DOT, SDA, CERTESS) TRDs provide qualities and functionality to the surface of the treated material.
