Corrosion performance of duplex treatments based on plasma nitriding and PAPVD TiAlN coating

Hot Corrosion & Erosion Problems in Coal Based Power Plants in India and Possible Solutions – A Review

“…The process was quite successful and the coating exhibit better corrosion resistance. Sugehis Liscano et al [44] have studied corrosion performance of duplex treatments based on plasma nitriding and PAPVD (Plasma Assisted physical vapour deposition)…”

Influence of Treatment Sequence on Tribological Performance of Duplex Surface-Treated AISI 1045 Steel

“…Among various hard face layers, nitride layers most importantly improve the load-bearing capacity of the surface; also, they can enhance the wear and corrosion resistance [6,7]. A wide range of coating systems such as AlN [8], CrN [9], TiAlN [10,11], CrAlN [12], and TiN [13,14] have been applied on steel using the duplex surface treating method. In addition, TiN coatings have found extensive industrial applications, such as coatings on mandrels, drawing dies, cutting tools, molds, gears, and bearings [15,16], as they offer high hardness, wear, and corrosion resistance [17,18]; also, good thermal and electrical conductivities should be noted [19].…”

Micro-Scale Abrasive Wear Testing of CrN Duplex PVD Coating on Pre-Nitrided Tool Steel

“…Duplex surface treatments have found extensive use in tribological applications because of their low friction and adequate balance between surface hardness, shear stress resistance, fracture toughness and load bearing capacity [7][8][9] . In addition, due to their chemical inertness, PVD coatings are very well suited for resisting corrosion [10][11][12][13][14] . Some typical application examples of duplex surface treatments may be found in forming dies, casting molds, cutting tools and prosthetic implants [15][16][17][18][19][20] .…”
