Abstract

Boriranje je postupak kojim na površini boriranog materijala nastaju boridi koji su visoke tvrdoće čime se ostvaruje otpornost na abrazijsko trošenje, otpornost na adhezijsko trošenje te postojanost na koroziju uslijed djelovanja kiselina. Boriranjem se višestruko produljuje radni vijek strojnih elemenata. Postupci boriranja i proizvodi s boriranim slojevima se štite kao intelektualno vlasništvo, prvenstveno patentom, ukoliko zadovolje određene uvjete. Statističkom analizom patentnih dokumenata odnosno izradom izvještaja o patentnom krajoliku, može se pratiti pregled patentne aktivnosti i trendova u jednom području tehnologije kojim se složene informacije mogu predstaviti na jasan i pristupačan način.
U radu su utvrđeni tehnologijski trendovi postupaka boriranja i poboljšanje svojstava boriranih slojeva analiziranjem patentnih dokumenata predmetnog područja u relevantnim bazama podataka. Prikazan je razvoj tehnologije boriranja ovisno o vremenu, zemlji autora/izumitelja, pravnom statusu prijavitelja patenta te su provedene i druge analize. Posebna pažnja pridana je analizi patentne dokumentacije predane kineskom patentnom uredu gdje se nalazi dvije trećine prijava. Dobiveni rezultati su uspoređeni s rezultatima bibliometrijske analize relevantnih znanstvenih članaka. Provedena je komparativna analiza patentne i nepatentne literature te je analiziran njihov međuodnos.
Eksperimentalno je provjereno je li odabrana patentna prijava dovoljno otkrivena i jasna da bi se izum mogao izvesti (što je jedan od zakonskih zahtjeva) na način da se proizvod (čelik) iz prijave borirao prema postupku navedenom u opisu izuma te su ispitivanjem poboljšanih svojstava evaluirani rezultati navedeni u samoj patentnoj prijavi.

Abstract (english)

Boriding is a process by which borides are formed on the surface of the borided material, which are of high hardness, thus achieving resistance to abrasive wear, resistance to adhesive wear and resistance to corrosion due to the action of acids. Boring extends the working life of machine elements many times over. Boriding processes and products with borided layers are protected as intellectual property, primarily by patent, if they meet certain conditions. By statistical analysis of patent documents, i.e. creation of patent landscape reports, an overview of patent activity and trends in one area of technology can be followed, by which complex information can be presented in a clear and accessible way.
The technological trends of boronizing procedures and impored properties of boronized layers were determined by analyzing patent documents of the subject area in the relevant databases. The development of boriding technology depending on the time, the country of the author/inventor, the legal status of the patent applicant and other analyzes is presented. Special attention was paid to the analysis of the patent documents submitted to the Chinese Patent Office, where two thirds of the applications were submitted. The obtained results were compared with the results of bibliometric analysis of relevant scientific articles. A comparative analysis of patent and non-patent literature was conducted and their relationship was analyzed.
It was experimentally verified whether the selected patent application was sufficiently disclosed and clear that the invention could be carried out (which is one of the legal requirements) in such a way that the product (steel) from the application was produced according to the process specified in the description of the invention, and that by examining the improved properties were evaluated by the results stated in the patent application itself.
