چکیده مقاله :
یکی از بهترین روش های مؤثر برای بهبود مقاومت به سایش و سختی فولادهای زنگ نزن اعمال پوشش های سطحی است. از جمله این پوشش ها، پوشش های آلیاژی و کامپوزیتی پایه نیکل هستند. در این تحقیق، پوشش کامپوزیتی نیکل- فسفر- اکسیدتیتانیوم با استفاده از روش آبکاری الکتریکی بر روی فولاد زنگ نزن AISI 430 ایجاد شد. تأثیر pH آبکاری (3، 5/3 و 4) بر روی میکروساختار و میکروسختی و رفتار سایشی آنها مورد بررسی قرار گرفت. به منظور تعیین فازهای موجود و محاسبه اندازه دانه، از روش آنالیز پرتو ایکس (XRD) استفاده شد. مشخصه یابی پوشش به کمک میکروسکوپ الکترونی روبشی (SEM) صورت پذیرفت. میکروسختی نمونههای بدون پوشش و پوششدار توسط دستگاه ریزسختی سنج ویکرز اندازهگیری شد. همچنین مقاومت سایشی نمونه های بدون پوشش و پوشش داده شده با کامپوزیت نیکل- فسفر- اکسیدتیتانیوم با استفاده از آزمون پین بر روی دیسک بررسی شد. نتایج آنالیز پرتو ایکس نشان داد که افزایش pH باعث افزایش اندازه دانه ها میشود. همچنین نتایج آزمون میکروسختی و پین بر روی دیسک نشان داد افزایش pH موجب کاهش میکروسختی و مقاومت سایشی میشود. بیشترین سختی (18/618 ویکرز) مربوط به پوشش ایجاد شده در 3pH=، با غلظت gr/L 40TiO2= بود. همچنین بیشترین مقاومت به سایش و کمترین کاهش وزن ( mg15/0) نیز مربوط به همین پوشش بود.
One of the best ways to improve the abrasion resistance and toughness of stainless steels is to apply surface coatings. Among these coatings are nickel base alloy and composite coatings. In this research, nickel-phosphorus-titanium oxide coatings were developed using electrical plating technique and the effect of pH (3, 3.5 and 4) on microstructure and their wear and tear behavior were studied. In this research, nickel phosphorus-titanium oxide coating was deposited onto the AISI 430 steel using electrical plating technique and the effect of TiO2 particles concentration on microstructure and wear behavior was studied. X-ray analysis (XRD) was used to determine the available phases and calculate grain size. Characterization of the coating was performed using SEM (Scanning Electron Microscopy). The michardness was measured by Vickers microhardness device. To test the abrasion resistance of the phosphorus-titanium oxide coated and uncoated samples, a pin on the disk test was used. The results of X-ray analysis showed that the increase of pH causes the increase of grain size. Also the results of microhardness and pin on disk tests showed the increase of pH causes decrease of microhardness and abrasion resistance. The highest hardness (618.18 Vickers) was related to the coating created at pH =3 and TiO2 =40 gr / L. The highest wear resistance and lowest weight loss (0.15 mg) were also observed in the same coating.
