González-García, Y. (author), García, S.J. (author), Fischer, H.R. (author), Hughes, A.E. (author), Mol, J.M.C. (author)In this work local electrochemical techniques are introduced as powerful and complementary techniques for the in-situ evaluation of self-healing systems applied for the protection of metals against corrosion. Scanning vibrating electrode technique (SVET) and scanning electrochemical microscopy (SECM) are employed for the evaluation of coatings...conference paper 2011

(author), TNO Kwaliteit van Leven (author)Nowadays Pulsed Electric Field (PEF) treatment of food needs to be performed prior to packaging, either hygienic or aseptic packaging is necessary. New techniques for PEF treatment after packaging can be considered when plastic conductive (film) electrodes can be integrated within the package, so that the package and the product can be treated...article 2010

Landucci, G. (author), Molag, M. (author), Reinders, J. (author), Cozzani, V. (author), TNO Bouw en Ondergrond (author)Two large-scale diesel pool fire engulfment tests were carried out on LPG tanks protected with intumescing materials to test the effectiveness of thermal coatings in the prevention of hot BLEVE accidental scenarios in the road and rail transport of LPG. A specific test protocol was defined to enhance reproducibility of experimental tests. The...article 2009

Lodhi, Z.F. (author), Mol, J.M.C. (author), Hovestad, A. (author), 't Hoen-Velterop, L. (author), Terryn, H. (author), de Wit, J.H.W. (author), TNO Industrie en Techniek (author)The corrosion properties of electrodeposited zinc-cobalt-iron (Zn-Co-Fe) alloys (up to 40 wt.% Co and 1 wt.% Fe) on steel were studied by using various electrochemical techniques and compared with zinc (Zn) and cadmium (Cd) coatings in 3.5% NaCl solution. It was found that with an increase in Co content in the coating the open circuit potential ...article 2009

Hoeflaak, M. (author), de Ruiter, B. (author), Maas, J.H. (author), TNO Industrie en Techniek (author)In 2001, TNO completed a major project on the performance of more than 30 different coil coating systems [1, 2]. The main objective was to investigate corrosion protection through artificial corrosion tests and outdoor exposures, which were continued for up to ten years. Gloss measurements were performed to obtain information on the weathering...article 2006

Carvalho, N.J.M. (author), Huis in 't Veld, A.J. (author), de Hosson, J.T. (author), TNO Industrie (author)Titanium-nitrogen (TiN) films were Physical Vapour Deposited (PVD) on tool steel substrates with different hardness and surface roughness, in a Bai 640R unit using a triode ion plating (e-gun) with a high plasma density. The coated substrates were submitted to a rolling contact fatigue test technique (modified pin-on-ring test) to obtain some...article 1998

de Vries, J. (author), Polder, R.B. (author), TNO Bouw (author)As part of the maintenance policy of the dutch Ministry of Transport, Civil Engineering Division, hydrophobic treatment of concrete was considered as an additional protective measure against penetration of aggressive substances, for instance deicing salts in bridge decks. A set of tests was designed to determine the performance of commercial...article 1997

van der Weijde, D.H. (author), van Westing, E.P.M. (author), de Wit, J.H.W. (author), Centraal Instituut voor Materiaal Onderzoek TNO (author)Electrochemical impedance spectroscopy (EIS) has been described by several authors as a technique to measure delamination of organic coatings. The interpretation of EIS data can be performed in several ways. In this paper two methods are critically compared. These two methods are the breakpoint frequency method (BF) as described and used by...article 1994
