Increasing the life cycle of cutting tools by laser alloying in combination with thin film technologies

Objective



Cutting tools such as circular saw blades have to resist complex mechanical and tribological stresses particularly in the area of the cutting edge. This proposal describes the development and optimization of a manufacturing program for cutting tools in which innovative technologies such as laser alloying in combination with thin film processing will be integrated. Main objective of this research project will be the increase of heat and wear resistance of circular saw blades. Therefore, locally alloying of heat and wear resistant filler materials on inexpensive iron-based materials will be carried out. Depending on specific requirements, hard coating (for instance TiN) by thin film technologies such as plasma CVD or PVD is planned. In addition, the employment of thin films such as MoS2, which cause decreasing friction, is conceivable. This will have to be worked out during a feasibility study in Step 1. The following advantages can be expected by using laser alloying in combination with thin film technologies during the manufacturing of cutting tools: - Increased wear resistance and increased cutting rate respectively - Employment of inexpensive base materials which will be locally surface modified - Decreased use of cooling liquids and lubricants The performance of this new generation of saw blades will be investigated as well as economic aspects.
