“…Therefore, low-temperature nitriding and carburizing could be applied to austenitic stainless steel plates used under severe friction conditions. In addition, these treatments restrict the formation of chromium nitride or carbide, maintaining the corrosion resistance [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17].…”

Cold-sprayed AISI 316L stainless steel coatings are treated to form an austenite phase with excessive dissolved nitrogen (known as the S-phase) by plasma nitriding at temperatures below 450 • C. The S-phase is a hard and wear-resistant layer with high corrosion resistance. However, the S-phase layer formed after only nitriding is thin and the hardness abruptly decreases at a certain depth; it lacks mechanical reliability. We examined two types of combined low-temperature plasma treatment to enhance the mechanical reliability of the S-phase layer: (i) sequential and (ii) simultaneous. In the sequential plasma treatment, the carburizing step was followed by nitriding. In the simultaneous treatment, the nitriding and carburizing steps were conducted at the same time. Both combined plasma treatments succeeded in thickening the S-phase layers and changed the hardness depth profiles to decrease smoothly. In addition, anodic polarization measurements indicated that sequential treatment involving carburizing followed by nitriding for 2 h each resulted in high corrosion resistance.However, plasma-sprayed stainless steel coatings include oxide layers, cracks, and pores in their structure, which deteriorate the corrosion resistance considerably.Cold-spraying is not a fusing process but a solid particle stacking process. Hence, cold-sprayed coatings are without any oxides, similar to a bulk steel structure [23]. It was reported that thick cold-sprayed 316L stainless steel coatings show electrochemical polarization behavior similar to bulk stainless steels [24]. Therefore, it is expected that cold-sprayed AISI 316L coatings can be applied as corrosion protective coatings. Additionally, Villa et al. reported that cold-sprayed 316L coatings can be hardened by cold working during the deposition process, which can also result in increased strength, and the abrasive wear resistance of the coating is in the same order of magnitude as that of coatings produced by HVOF [25]. However, the hardness of the 316L coatings was 358 ± 36 HVN, which is insufficient to apply under severe wear conditions.We have previously reported low-temperature plasma nitriding of cold-sprayed AISI 316L coatings to successfully improve the Vickers hardness to 1200 HV [26]. In particular, remelted AISI 316L coatings by a postlaser treatment had excellent corrosion protection for ordinary steel substrates due to a dense microstructure.However, there is a concern that S-phase layers formed by nitriding without carburizing could be delaminated when an external force is applied, because the hardness of the S-phase layers declines drastically at a certain depth. Low-temperature treatments combining nitriding and carburizing have been reported to result in a milder hardness distribution (with hardness not declining drastically), excellent wear resistance, and thickening of the S-phase layers. There are two types of combined treatments-(i) sequential and (ii) simultaneous. In the sequential treatment, carburizing is followed by nitriding [27][28][29]. Meanwhile, in ...

Wstęp: Przedmiotem badań była ocena fizykomechanicznych właściwości bioceramiki hydroksyapatytowej (HAp) natryskiwanej plazmowo na podłoże tytanowe typu Ti-grade 2 (CP-Ti). Ten sposób nanoszenia powłoki wykorzystywany jest w procesie nakładania warstw na implanty dla lepszego związania ich z tkanką kostną. Materiał i metody: W celu przeprowadzenia badania przygotowano hydroksyapatyt według technologii chemii mokrej przez wydzielenie z roztworu substancji w postaci stałej. Następnie opracowano podłoże tytanowe, na które naniesiono hydroksyapatyt techniką natryskiwania plazmowego. Wyniki: Przeprowadzone badania pozwalają stwierdzić, iż właściwości otrzymanej powłoki mogą być wykorzystywane do pokrycia dużych powierzchni implantów o dowolnym kształcie. Wnioski: Podczas badań dotyczących fizykomechanicznych parametrów hydroksyapatytowych powłok odnotowano, iż wykazują one wystarczające właściwości mechaniczne do stosowania w implantologii. Dalszym celem badań będzie właściwy dobór technologicznych parametrów natrysku powłok, który pozwoli zwiększyć adhezje i kohezje powłok HAp.

“…In many cases, the most commonly used methods for wear testing of the metallic biomaterials are not particularly aimed on reflecting the actual working conditions of an artificial joint. For example, for tribological testing purposes, the ball-on-disc [13][14][15], pin-on-disc [13,15] and block-on-disc [16] configuration might be used. Moreover, the lubricating conditions [14,[17][18][19][20], the applied load [13,15,20], the sliding velocity [13,21] as well as the temperature [16,19], may differ.…”

Nowadays, metallic alloys are extensively used in wear-related biomedical applications. However, it was shown that one of the factors which may contribute to the premature implant failure is the temperature effect caused by the sliding action between the bearing surfaces. Nevertheless, there are not many papers where the wear-related temperature phenomena of biomedical alloys are discussed. Thus, in our paper, we present findings from the tribological tests of the model metallic biomaterials-316L steel, CoCrMo alloy and Ti gr. 2. In our study, the temperature alterations induced by the wear action of the examined materials were analyzed. According to the findings, the temperature response of the biomedical alloys is tribological pair dependent. While the mass loss of the tribological pair 316L-316L steel was the slightest, at the same time the temperature increase was the greatest. Based on the presented findings, further analyses in friction-induced temperature response of biomedical alloys is recommended.
