Preparation and Properties of Ag-Based Electrical Contact Material Reinforced by Ti3AlC2 Ceramic and its Derivative Ti3C2Tx

“…Over the past decades, MAX phase [8][9][10] , combining excellent properties of metal and ceramic, has been widely investigated in various elds [11][12][13][14][15][16] . As a representative member of MAX family, Ti 3 AlC 2 has been used to reinforce Ag matrix as the electrical contact material [17][18][19][20][21] . However, the electrical resistivity of the Ag/Ti 3 AlC 2 composite is not satisfactory, which is initially attributed to the inter-diffusion between Al layer and Ag matrix [22] .…”

Erosion Behavior of a Cu-Ti3AlC2 Cathode by Multi-Electric Arc

“…In addition, the coefficient of thermal expansion of Ti 3 Al(Si)C 2 (9.0–9.2 × 10 −6 K −1 ) is close to that of pure Cu (8.5 × 10 −6 ·K −1 ). Therefore, the outstanding properties of Ti 3 Al(Si)C 2 make reinforcement possible for the Cu matrix to use as a potential brush and sliding electrical contact material [16,17,18]. Tian et al [19] found that with the increase of Ti 3 AlC 2 content, the number of surface cracks increased after arc ablation.…”

“…It was found that Ti 3 SiC 2 turned into TiC x after arc ablation. Previous work showed that Ti 3 AlC 2 material had the effect of dispersing arc under atmospheric conditions, and the dispersing effect was better with higher Ti 3 AlC 2 content [17,18,20,21]. Sun et al [19,22,23,24,25,26] systematically studied the wettability between the Ag and MAX phases.…”
