Embodiment 1
[0029] The chemical composition of the FV520B material used in this example: C: 0.04wt.%; Si: 0.42wt.%; Mn: 0.74wt.%; S: 0.005wt.%; P: 0.021wt.%; Cr: 13.80wt.%. %; Mo: 1.46wt.%; Ni: 5.39wt.%; Cu: 1.49wt.%; Nb: 0.30wt.%; It is subjected to ion nitriding heat treatment, including the following steps:
[0030] (1) solution treatment, at 1050 ℃, heat preservation for 2 hours, then air cooling;
[0031] (2) Adjustment treatment, heat preservation at 850°C for 2.5 hours, and then oil cooling;
[0032] (3) Ion nitriding treatment, ion nitriding at 530°C for 18.0 hours, furnace cooling down to 200°C, and then out of the furnace and air cooling;
Embodiment 2
[0041] The chemical composition of the FV520B material used in this example: C: 0.04wt.%; Si: 0.42wt.%; Mn: 0.74wt.%; S: 0.005wt.%; P: 0.021wt.%; Cr: 13.80wt.%. %; Mo: 1.46wt.%; Ni: 5.39wt.%; Cu: 1.49wt.%; Nb: 0.30wt.%; It is subjected to ion nitriding heat treatment, including the following steps:
[0042] (1) solution treatment, at 1050 ℃, heat preservation for 2 hours, then air cooling;
[0043] (2) Adjustment treatment, heat preservation at 850°C for 2.5 hours, and then oil cooling;
[0044] (3) Ion nitriding treatment, ion nitriding at 530°C for 20.0 hours, furnace cooling down to 200°C, and then air cooling out of the furnace;
Embodiment 3
[0053] The chemical composition of the FV520B material used in this example: C: 0.04wt.%; Si: 0.42wt.%; Mn: 0.74wt.%; S: 0.005wt.%; P: 0.021wt.%; Cr: 13.80wt.% %; Mo: 1.46wt.%; Ni: 5.39wt.%; Cu: 1.49wt.%; Nb: 0.30wt.%; Ion nitriding heat treatment at different temperatures was carried out, including the following steps:
[0054] (1) solution treatment, at 1050 ℃, heat preservation for 2 hours, then air cooling;
[0055] (2) Adjustment treatment, heat preservation at 850°C for 2.5 hours, and then oil cooling;
[0056] (3) Ion nitriding treatment, ion nitriding at 500°C for 20.0 hours, furnace cooling down to 200°C, and then out of the furnace and air cooling;
[0057] See Table 5 for the infiltrated layer index of the tested example 3FV520B material after ion nitriding heat treatment, ion nitriding at 500°C also has a better infiltrated layer depth, the surface hardness is greatly improved, and the core hardness is also higher.
