Objective
Today, more and more applications in various industrial branches (transport, tools and more generally mechanics) have important needs in wear resistance. In aerospace, mining, drilling or offshore applications, the parts facing real hard wear conditions are large and are done in resistant ( but expensive) materials. Furthermore the major part of industrial tools used or warn is destroyed and replaced by new ones leading to a considerable amount of raw materials wastes and economical loss. This represents a cost of around 1 billion ECUs per year in Europe. Cladding is wider in its application and includes the protection of parts against corrosion. Cladding also includes the reconstruction of worn out parts with a usual alloy. The laser cladding technique is currently using a CO2 laser combined with a mobile bench which enables an automated process. The main disadvantages of this technique are the size and weight of a CO2 laser cladding equipment, the reflection on metals to be cladded which lead to a considerable energy loss during this process the size of the equipment limits the use only to simple shapes The high power laser diode will improve flexibility in laser cladding thanks to its smaller size, and weight compared to a CO2 one and also because the investment to be made will be lowered. Association of high power laser diode with cladding technique will therefore have positive impact on the following: Initial investment cost will be divided by two: the whole laser cladding equipment price willbelowered clown from tol 000 000 ECUs (equipment and laserCO2) to100 000 ECUs (with the new robot and laser diode). In fact, laser diode has just appeared on the industrial market they are commercially available with a power of 3 kW which enables its use in cladding application. Consequently, our project targets to develop a new automated laser cladding technique based on high power laser diode and consequently improvement of wear characteristics of parts and their possible repairing. This will be done thanks to two developments: - development of optical means to focus the laser beam - development of the linked bench system to automate the cladding operation. Areas if the Brite Euram workprogramme covered by this proposal are the following: Applications of appropriate automation, intelligent assembly, mechatronics and microsystem technologies to improve cleanliness, reliability, repeatability and control of production processes, and to replace repetitive, tedious, and dangerous functions, while optimising the use of human labour. New systems will take into consideration the suitability of the working environment and enable the application of new production approaches including technologies for new methods of construction. Other areas covered by the proposal: 1. l.7.M :Development of new and improved production systems able to provide increased speed and accuracy of cutting, forming, rolling, casting, shaping, welding, surface treatment machining and other manufacturing operation. 2.1.3.M:Environmentally compatible surface engineering, coating (both organic and inorganic) and joining technologies to improve durability, performance, and functionality (e.g. physical, chemical and biochemical characteristics).
