Thermal Spraying Processes and Amorphous Alloys: Macro-Indicators of Patent Activity

Abstract

Thermal spraying processes allows high cooling rates and can favor the formation of amorphous microstructures. Amorphous metallic coatings can result in superior mechanical and functional properties. To follow new technological development and innovation paths, indicators based on patent data can be assembled to support technological forecasting assessments and decision making. This study mapped the technological development on amorphous alloys processed by thermal spraying using patent indicators from documents indexed in the Derwent Innovations Index database between the years 1997 and 2014. We evaluate the patent activity, the role of countries, the main technological subdomains and markets of interest, as well as the main metallic alloys explored as coating. We conclude that new technological developments should be expected in near future and these advances both in amorphous alloys and thermal spraying shall be constantly monitored in the coming years.

Development of Fe-based glass former alloys for thermal spray coatings with optimized corrosion and wear properties

“…Also, recent reviews of Fe-based glassy coatings have been published [75][76][77] and the number of publications and citations have grown remarkably, reaching over 4,000 cumulative citations for specific Fe-based thermally sprayed metallic glass coating. Indeed, the topic is also present in patents, as indicated in recent studies that demonstrate the applied potential of Fe-based metallic glass alloys [78] and coatings [79].…”

Research Community Analytic Tool Based on Topic Modeling and Network Analysis

“…Данные для построения графов могут быть загружены из файлов или через API поддерживаемых наукометрических баз, таких как WoS, Scopus, Dimensions, CrossRef, Medline. Например, авторы [22] применили его для визуализации кластеров патентов, в которых встречались аморфные сплавы, чтобы проанализировать тенденции патентного ландшафта в этой области металлургии. В [23] с помощью VOSviewer исследовалось взаимодействие авторов американского сообщества массспектрометрии -исследование показало значительные отличия в публикационной активности университетов и лабораторий, а также, что довольно ожидаемо, -более частое соавторство между сотрудниками, работающими в одном учреждении.…”

Mapeamento Das Organizações Brasileiras E Estrangeiras Atuantes Em Vidros Metálicos

“…O mapeamento das organizações interessadas em metais amorfos foi realizado com base no procedimento experimental apresentado na Figura 1. As publicações científicas brasileiras foram recuperadas com a aplicação de uma expressão de busca elaborada com base em palavras chave que se referem ao tema, sendo a mesma desenvolvida e já aplicada em outras pesquisas conduzida pelos autores [1,7,15]. A busca foi realizada no campo tópico da base de dados Web of Science, que procura pelos termos no título, resumo e palavras chave dos registros bibliográficos indexados.…”

“…[4][5][6]). O Brasil também tem se envolvido em estudos de proposição, fabricação, caracterização e aplicação de tais ligadas, embora num contexto acadêmico [1,7]. O potencial de inovação de processos e de produtos destas ligas metálicas especiais torna necessário o mapeamento das organizações que atuam tanto nas pesquisas científicas como nas pesquisas tecnológicas, de modo a facilitar a inovação por meio da aproximação entre universidade e empresa.…”
