Kouřil, M. ; Boháčková, T. ; Švadlena, J. ; Prošek, T. ; Strachotová, K. Ch. ; Kreislová, K. ; Fialová, P. ; Majtás, Dušan
The aim of the methodology is to specify the procedures for determining the corrosion aggressiveness of internal atmospheres for the area of historic preservation, especially in objects with an increased risk of volatile occurrence\norganic substances, which can endanger metal and other objects with their corrosive aggressiveness cultural and historical value. Target locations are, for example, archives, libraries, exhibition spaces and depositories of museums and churches and target objects of lead seals, organ pipes containing lead, stained glass windows, tin-lead dishes, technical monuments with lead solders, printing letters, etc.

Metodika klasifikace korozní agresivity vnitřních prostředí znečištěných těkavými organickými kyselinami
Kouřil, Milan ; Boháčková, Tereza ; Švadlena, Jan ; Prošek, Tomáš ; Strachotová, Kristýna Charlotte ; Kreislová, Kateřina ; Fialová, Pavlína ; Majtás, Dušan
Corrosion of metal historical artefacts by volatile organic acids (VOA) is common in indoor atmospheres where VOA sources are present and where insufficient measures are taken to eliminate the aggressive effects of these substances on metals. The procedure for determining the corrosion aggressiveness of indoor atmospheres towards metals is defined in three parts of the standard EN ISO 11844 'Corrosion of metals and alloys - Classification of indoor atmospheres with low corrosion aggressivity'. The corrosion aggressivity classes (IC1 to IC5) are based, among others, on the determination of the mass loss of corrosion coupons of silver, copper, steel, zinc and lead. Lead was included in the first part of EN ISO 11844-1 in 2021, based on the results of the NAKI II project "Methodology for the classification of corrosion aggressiveness of indoor environments for lead alloy collectors" (DG18P02OVV050), as a metal specifically sensitive to the presence of volatile organic acids. The aim of the methodology is to specify the procedures for determining the corrosion aggressivity of indoor atmospheres for the field of conservation, especially in objects with a higher risk of the presence of volatile organic compounds, which can threaten metallic monuments by their corrosion aggressivity. Thus, target locations are, for example, archives, libraries, exhibition spaces and depositories of museums and churches, and target objects are lead seals, organ pipes containing lead, stained glass, pewter utensils, etc. The sources of VOCs include a range of materials that make up common furnishings in indoor environments - wood paneling and ceilings, furniture, cabinets, display cases, as well as other items on display or stored.

Klasifikace korozního poškození historického olova a systém prostředků pro jeho konzervaci
Kouřil, Milan ; Ďurovič, Michal ; Bartl, Benjamin ; Strachotová, Kristýna Charlotte ; Msallamová, Šárka
Mnohé muzejní a archivní instituce se v současnosti potkávají s problematikou koroze olověných sbírkových předmětů, uložených v depozitářích, způsobenou citlivostí olova vůči těkavým organickým sloučeninám (VOC), zejména vůči kyselině octové. Zvláštní skupinou těchto olověných předmětů jsou olověné buly (kovové pečeti), které bývají obvykle připojeny k pergamenovým listinám pomocí textilního závěsného materiálu. Metodika zavádí systém kategorizace korozního poškození olověných pečetí a hodnocení podmínek jejich uložení a navrhuje postupy konzervačních opatření vhodné pro možné varianty výsledky průzkumu stavu pečetí a expozičních podmínek. Navržené konzervační postupy jsou založeny především na eliminaci agresivních složek prostředí volbou vhodných obalových materiálů a použitím sorbentů.

Rotary flash hardening with help of electron beam and laser radiation
Klusáček, Martin ; Jan, Vít (referee) ; Kouřil, Miloslav (advisor)
This master thesis deals with surface hardening of steels, especially with rotary flash hardening of 42CrMo4 steel (WNr 1.3563, ČSN 15142). In this method homogenous heating of whole surface occurs during a very fast rotation of the component. In the theoretical part of this thesis the most common methods of surface hardening are described, with focus on laser and electron beam technologies. In the experimental part special device for this application was constructed. Rotary flash hardening was done using different radiation source and experimantal device parameters. The hardened surface layer of maximal thickness of 0,7 mm and width of 5,6 mm was achieved using laser beam. Results with electron beam were way better, because this technology allows to control the distribution of power along the beam width in order to improve the width/thickness ratio of hardened layer. Using this method maximal layer thickness of 1,4 mm and width of 13,4 mm was achieved.
