Special Issue Information

Dear Colleagues,

Wear- and corrosion-resistant composites and coatings based on these materials are widely used in aerospace engineering, power generation, biotechnology, and medicine. Composite materials on a metal or polymer base hardened with second phases of different nature and synthesized using special processing technologies allow the formation of final products with unique properties. The continuously growing market stimulates material scientists, process engineers, and software developers to create new composites with further improved chemical formulae, phase balance, and properties. This requires new knowledge on the fundamental aspects of chemical design and the optimization of processing parameters.

Research on advanced composites with unique properties, specific microstructure and phase composition, as well as the study of structure–property–performance relationships is a rapidly growing field. These studies frequently require a substantial experimental database. However, recent achievements in computer modeling significantly speed up the design process, reducing the time between the idea creation and the product manufacturing and sales. Modern software packages allow quick optimization of chemical composition, microstructure, and processing parameters. This brings invaluable help in case of such new technologies as additive manufacturing (3D printing), where the experimental database is relatively small compared to traditional technologies based on powder sintering.

In this Issue, we address the following topics:

  • Recent advancements in chemistry of composite materials leading to increased wear and corrosion resistance;
  • Microstructure and phase balance, in particular effect of the spatial distribution and morphology of strengthening agents (fibers, whiskers, particles) on properties;
  • New methods and machines for testing wear and corrosion resistance;
  • Computer modeling software for material and process design;
  • Novel processing technologies for composite materials, such as additive manufacturing, powder spray, laser treatment.

The machining of composite materials has been an area of intense research for the past couple of decades due to its wide range of applications, from automobiles to air crafts or from boats to nuclear systems. Non-conventional machining, especially electric discharge machining (EDM), is found to be a good machining option for meeting the required outputs. To overcome the challenges of machining complex shapes, wire electric discharge machining (WEDM) was developed. Al6351 composites was observed to be extensively used in nuclear applications. Therefore, identifying the kerf width and surface roughness are important criteria for the dimensional accuracy of the final product. The present work aims at predicting the behavior of the two major machining parameters which are kerf width and surface roughness of Al6351 composites in wire EDM by creating a mathematical model using ANOVA for different combinations of the reinforcements and comparing the variations in the coefficients for different combinations of reinforcements. The developed model has been validated by conducting similar set of experiments in Al6351-5% SiC-1% B4C hybrid composite. From the work, it was identified that pulse on time and current are the major contributing factor for kerf width and wire feed rate was observed to be contributing to the surface roughness. The validation results show an average variation of 8.17% for kerf width and 11.27% for surface roughness. The work can be successfully utilized for prediction of the kerf width and surface roughness of the composites manufactured with Al6351 as the base matrix material. Full article
