Special Issue "Hardfacing of Metals and Alloys"
A special issue of Metals (ISSN 2075-4701).
Deadline for manuscript submissions: 31 March 2021.
Interests: Thermal and metallurgical fundamentals of welding. Theory, modeling and experimental investigation of welding processes. Technological aspects of welding, surfacing by welding (hardfacing, rebuilding). Thermomechanical states of welding, laser and heat treatment processes (temperature field, phase changes, strains and stresses, analytical and numerical methods, modeling). Mechanics of materials.
Hardfacing is the process of surfacing with implementation of welding techniques (methods) for the deposition of harder or tougher materials on the base metal. Hardfacing is a widely used method to protect the surfaces of tools or machine parts against severe wear, corrosion, or oxidation. The methods of hardfacing are important in the application of welding techniques and technological development for the manufacturing of new components, their repair, and extension of their service life for most industries.
The progress in welding methods and material engineering over recent years demands systematic studies of welding methods and consumables applied to hardfacing. The optimization of hardfacing processes require characterization of the relevant welding parameters, such as, e.g., heat input, shielding gases, and preheating temperature. The modern materials for consumables allow for deposition of layers with a wide spectrum of chemical compositions and variable types of micro- and nanostructured precipitates of ultra-hard carbides or borides which improve wear resistance. The optimum alloy selection is made considering the component service conditions and service performance.
The purpose of this Special Issue is to present the latest developments in the research on hardfacing technologies of metals and alloys.
The main topics of interest include but are not limited to the following hardfacing techniques
- Shielded metal arc welding (SMAW)
- Gas metal arc welding (GMAW), including both gas-shielded and open arc welding
- Oxyfuel welding (OFW)
- Submerged arc welding (SAW)
- Electroslag welding (ESW)
- Plasma transferred arc welding (PTAW), also called powder plasma welding
- Thermal spraying
- Laser cladding

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Metals is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
