Abstract

Mechanical properties of ferrochrome based hardfacing layers coated on AISI 1020 steel obtained by the aid of Plasma Transfer Arc (PTA) was experimentally studied. Ferrochrome powders were mixed with sodium silicate gel to avoid spreading. The mixture was laid to 1.5 × 8 × 100 mm slots machined on AISI 1020 steel. Hardfacing layer was performed by PTA process under pure Argon as protective gas with 130 A/20 V power supply. Scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), micro hardness and abrasive tests were employed for the evaluation of ferrochrome alloyed coating. Hardfacing was successfully performed under given conditions. Microstructural changes and formations (phases) significantly improved hardness, abrasive wear resistance and integrity of hardfacing layer.

Kurzfassung

Experimentell untersucht wurden die mechanischen Eigenschaften von durch Plasma-Pulver-Auftragschweißen (PTA) auf AISI 1020-Stahl aufgetragenen Hartstoffschichten auf Ferrochrombasis. Um ein Verlaufen zu vermeiden, wurde dem Ferrochrompulver Natriumsilikatgel beigemengt. Die Mischung wurde auf Einkerbungen einer Größe von 1,5 × 8 × 100 mm aufgetragen, die maschinell in den AISI 1020-Stahl eingearbeitet wurden. Die Hartstoffschicht wurde durch PTA-Schweißen mit reinem Argon als Schutzgas bei 130 A und 20 V aufgebracht. Rasterelektronenmikroskopie (REM), energiedispersive Spektroskopie (EDS), Mikrohärte- und Abriebprüfungen kamen zum Einsatz, um die Beschichtung aus Ferrochromlegierung auszuwerten. Die Auftragschweißung ist unter den gegebenen Bedingungen erfolgreich verlaufen. Mikrostrukturelle Veränderungen und Ausbildungen (Phasen) verbesserten Härte, Abriebverschleißfestigkeit und Unversehrtheit der Hartstoffschicht erheblich.
