Effect of intrinsic properties of ceramic coatings on fatigue behavior of Cr–Mo–V steels

An Updated Review of the Fatigue Behavior of Components Coated with Thin Hard Corrosion-Resistant Coatings

“…Cr-Mo-V steels used for high temperature steam turbine rotor components have been found to be base materials which can take advantage of coating deposition. The effects of wear-protective, heat-resistant and corrosive-resistant thin hard ceramic coatings on the fatigue behavior of steels were examined in [22,23]. In [22], Kim et al characterized the mechanical properties of TiN, TiCN and TiAlN deposited by arc ion plating on Cr-Mo-V steel and carried out both rotating bending tests and axial constant amplitude loading tests on CT samples up to high cycle fatigue lives.…”

“…The effects of wear-protective, heat-resistant and corrosive-resistant thin hard ceramic coatings on the fatigue behavior of steels were examined in [22,23]. In [22], Kim et al characterized the mechanical properties of TiN, TiCN and TiAlN deposited by arc ion plating on Cr-Mo-V steel and carried out both rotating bending tests and axial constant amplitude loading tests on CT samples up to high cycle fatigue lives. Good adhesion to the substrate was found and high compressive residual stresses from crystal growth were produced in the coating layers.…”

“…The most typical applications of thin hard coatings include protection of cutting tools, cold and hot stamping and extrusion dies [2][3][4], due to the improvement in surface performance granted by these coatings in terms of hardness, wear and corrosion resistance properties [5][6][7][8][9][10][11][12]. Thin hard coatings can have a positive influence on the fatigue and the corrosion fatigue behavior of mechanical components, especially for relatively hard steel substrates [13][14][15][16][17][18][19][20][21][22][23]. For these reasons, PVD and CVD coatings are nowadays adopted also for other advanced applications in addition to manufacturing, including but not limited to automotive components [24][25][26][27][28], aeronautic gas engines turbine and compressor blade protection [29,30] and biomedical applications, due to the improved corrosion protection and biocompatibility granted by thin hard coatings [31].…”

“…Despite of this aspect, the adoption of PVD and CVD coatings over these high strength-to-mass ratio alloys is crucial to grant new application fields to these materials, which are becoming critical in the design of lightweight and efficient vehicles and mechanical devices. In this review paper, the most recent experimental results related to fatigue and corrosion fatigue behavior on steel [13][14][15][16][17][18][19][20][21][22][23] and light alloy [34][35][36][37][38][39][40][41][42] substrates are presented, giving some precious indications to mechanical designers about possible trends of the fatigue and corrosion fatigue behavior of different substrate/coating couplings.…”

A Review of the Fatigue Behaviour of Components Coated with Thin Hard Corrosion-Resistant Coatings

“…The good tribological and anti-corrosion performances achievable with these deposits have been highlighted by several research studies [3][4][5][6][7][8][9][10]. Furthermore, these coatings can have an influence on the fatigue and the corrosionfatigue behaviour of mechanical components [11][12][13][14][15][16][17][18][19][20][21][22][23][24]. The residual stresses introduced by the deposition process are supposed to be mainly responsible for this.…”
