Abstract
Coatings of amorphous metallic alloys can be obtained using different thermal spraying processes, such as HVOF, plasma spraying, cold spraying and others. Although many studies focused on investigating scientific issues concerning apply amorphous metallic coatings using thermal spraying, less attention have been paid to evaluate how research institutes and companies are collaborating and influencing each other to promote new technologies. In this paper, we assessed the collaboration of organizations and the knowledge flow on this relatively new field using bibliometrics and science mapping. The method relies on scientific publications indexed in Web of Science and clustered into research areas using the CWTS Publication-level Classification System. These results provide useful insights about how players are organized and may be used in the context of R&D management, science policy and decision making.

Summary
1.1 Amorphous metallic alloys applied by thermal spraying processes. Amorphous or glass metallic alloys are a striking class of non-crystalline materials with great potential for industrial application and technological innovations due to their particular mechanical, magnetic or electrical properties. This special class of metals are generally obtained by the combination of engineered compositions - usually involving more than three metallic elements with large atomic size ratios - with processes that provides high cooling rates (102-106 K/s) in a manner that the disordered atomic configuration found in the melted liquid is maintained down to room temperature[1,2]. A feedstock material is heated by electrical or chemical means and the spray of molten or semi-molten particles is directed or accelerated
