Inffluence of Ion Beam Implantation on the Corrosion Properties of Stainless Steel

Investigation of Corrosion Properties and Composition of the Surface Formed on AISI 321 Stainless Steel by Ion Implantation

“…The necessary properties of all types of coatings are high adhesion, continuity, and resistance to aggressive media. A protective layer can be formed on the surface by various methods: electrochemical [3,4] and chemical ones [5,6], thermal diffusion [7,8], laser cladding [9,10], magnetron sputtering [11][12][13][14][15], plasma deposition [16], ion implantation [17][18][19][20][21], etc.…”

“…Ion implantation improves the physical and mechanical properties of the material surface (hardness, heat resistance, wear resistance, fatigue strength, corrosion resistance, etc.) [20,[26][27][28][29][30]. The main advantages of ion implantation include the absence of adhesion problems [31] (since ions are implanted into the material at an energy of about 106 eV) and no influence on the geometric dimensions of workpieces, which is relevant for cutting tools or threaded joints [32].…”

“…The present paper deals with the combined effect of aluminum, boron, and oxygen implantation on the corrosion resistance of the stainless steel without changing the geometric dimensions. The effectiveness of ion implantation against corrosion was established in references [17,20,45], but the chemical changes occurring in surface layers during implantation and that increase corrosion resistance are poorly understood.…”
