Liquid metal assisted cracking (LMAC) and so-called microcracking are limiting the application of hot-dip galvanized boron steels in direct press hardening process. This study addresses role steel hardenability on behavior ZnFe-coated (galvannealed) 22MnB5 22MnMoB8. Several soaking times forming start temperatures range 800–520 °C examined using a laboratory equipment with hat-profiled tool. Th...

To study the protective effect of thermal spraying cobalt-based carbide coatings on hot-dip galvanized sinker rolls, a WC-12Co coating was prepared 316 L stainless steel substrate using supersonic flame method. The corroded in molten liquid zinc at 430 °C to analyze service life and failure process. results show that provided good protection base metal. process Zn first diffused into reacted ch...

I . The effect of dietary copper deficiency on the distribution of Cu, zinc and iron between plasma, various soft tissues and bone was investigated in weanling male rats. 2. The concentration of Cu decreased in plasma, liver, kidney and femur, and the concentration in plasma correlated with that in all three organs. The total amount of Cu in the liver was reduced over the whole depletion period...

Mycobacterium avium subsp. paratuberculosis (Map) is the causative agent of Johne's disease, a chronic enteric infection that affects ruminants. Despite the ubiquitous occurrence of Mycobacterium sp. in nature and the fact that Johne's disease has been reported worldwide, little research has been done to assess its survival in agricultural environments. The goal of this 365-day study was to eva...

Rapid development of automotive industry brings also increased requirements for sheets properties, involving relatively high strength and good formability together with excellent corrosion resistance. Increasing requests for corrosion resistance lead to the production of coated car parts, protected mainly by zinc coatings. Whereas, majority of European producers of passenger cars use preferenti...
