This project aims at altering the conveyor speed for maximum productivity and modifying the oven in order to increase the efficiency of powder coating process involved in painting the components of lifts. The primary thing to be considered while modifying the oven is the heat source provided. Most of the industries use forced convection for heating up the product in order to cure the powder coating process. This project aims at providing infrared radiation as the heat source to cure the powder over the metal surface. Forced convection is advantageous for more complex shapes. But the components of lifts are not of complex shapes. So, it would be efficient to use infrared. The forced convection system requires long heat up time, high energy consumption, large floor area and some additional setups for air circulation inside the oven. Infrared radiation heating would eliminate these drawbacks. The infrared radiation would be absorbed by the material in order to heat up. This is more efficient in case of curing the powder coated parts. Because, in case of forced convection first the paint in form of powder is heated and then the heat is transferred to the metal surface. Whereas in case of infrared heating, the metal would be heated first and then it would be transferred towards the powder paint. In other words, we could say that the infrared radiation heating provides backward heating which would increase the efficiency and life of the paint coated. Temperature control and instant heating are also the advantages of infrared heating. Hence designing the infrared source for the given metal and powder specifications is done in this project.

Soil Disinfection

Soil is a favorable environment for many microorganisms, pathogenic bacteria, fungal spores, insect eggs due to the presence of nutrients and moisture in it. Soil treatment from pests and pathogens of agricultural crops for disinfection can be carried out by chemical, energy, thermal, biological methods. The most common method is thermal. This is because many pests and pathogens have a protein structure that is easily destroyed when the temperature increases, and the thermal effect can be obtained from various heat carriers. (Research purpose) The research purpose is in developing an energy-efficient method of soil disinfection using infrared radiation. (Materials and methods) The article shows the relation between the spectral thermoradiation characteristics of soil with characteristics of infrared emitters, namely the amount of applied heat, temperature, conductivity, soil moisture, and exposure time, to justify the rational mode of operation for decontamination of the soil. The article presents a mathematical model for this purpose based on known laws that determine the relationship between the necessary parameters. (Results and discussion) Authors offered a plant for soil disinfection with infrared radiation. It was found that the high energy efficiency of the installation is achieved by a high efficiency of infrared burners and infrared radiation affects directly the object of treatment, the soil. The article presents structural-logical and mathematical models of infrared power supply. (Conclusions) Analysis of the heating kinetics equation showed that the maximum permissible speeds for the process of infrared heating of the soil depend on its thermophysical properties, the maximum permissible temperature, the area and the required depth of warming of the soil. It was found that infrared heating and a device for disinfecting the soil in this way will allow energy-efficient, convenient and fast processing.

A new approach was developed for surface modification of metallic surface. By treating nano-zirconia particles and metal surface in different charge state, nano-zirconia particles can be dispersedly inlaid in metal surface owing to electrostatic and nanometer effects. By using this method, metal components of complex shapes, especially those having inside surfaces, might be easily improved, i.e., enhanced surface hardness and wear rate.

Machining Productivity

Laser-assisted machining (LAM) process is an effective method to facilitate material removal processes for difficult-to-cut materials. In LAM process, the mechanical strength of various materials is reduced by a laser heat source focused in front of the cutting tool during machining. Since the laser heat source is located ahead of the cutting tool, the workpiece is preheated by the heat source. This enables difficult-to-cut materials to be machined more easily with low cutting energy, increasing the machining productivity and accuracy. It is difficult to apply laser-assisted milling (LAMilling) to workpieces having complex shapes, because it is not easy to control laser preheating and the cutting tool path for three-dimensionally shaped workpieces. LAMilling has only been used in limited fields such as single-direction machining of flat surfaces. To apply this process in the industrial field, studies on workpieces having various shapes are needed. This study aims to develop a laser-assisted milling device having multiple axes and to investigate the machining characteristics of several difficult-to-cut materials.
