Powłoki intermetaliczne otrzymywane w procesie przetapiania i stopowania

Gontarz G., Golański D., Chmielewski T.

Przegląd Spawalnictwa

2015

R. 87, nr 9

77--81

Praca przedstawia dotychczasowe wyniki badań nad wytwarzaniem warstw intermetalicznych Fe-Al z fazami Ti- Al (Fe-Ti) za pomocą metod spawalniczych obejmujących przetapianie plazmowe powłok Al oraz stopowanie Al i Ti w procesie przetapiania podłoża metodą TiG AC. Przedstawiono badania mikrostruktury, analizy fazowej, mikrotwardości oraz naprężeń własnych.

The paper presents current research results on producing Fe-Al intermetallic layers with Ti-Al (Fe-Ti) phases by welding methods. The plasma remelting of Al coating and alloying of Al and Ti in the process of surface remelting by AC TIG method were used. The microstructure, phase analysis, microhardness and residual stress analysis have been performed.

The use of welding techniques in protection of welding structures against corrosion

The paper presents possibilities of using welding techniques as a means of protection from corrosion of materials for welding structures operating in power engineering industry, chemical industry and shipbuilding. Based on the example of an LNG installation, the potentials of weld overlaying in anti-corrosive protection of parts operating in LNG installations have been described. The weld overlaying technique enables building up of protective coatings, which not only protect material from corrosion resulting from the flow of more or less aggressive medium (e.g. water, exhaust gas) but also increase the performance life of thus “coated” elements due to the improved abrasion wear resistance of weld overlays. The weld overlaying process is equally well suitable in building of new structures as in the repair of damaged or worn out elements of water or power feeding installations.
