[0075] The diamond composite sheet sample used in this example is a product produced by Antai Steel Research Institute, the brand name is AGT1613×2.0-SU (for oil drilling), the cobalt removal depth of the diamond layer is 1 mm, and the quantity is 20 pieces.
[0076] The specific reinforcement processing methods are as follows:
[0077] Step 1. Clean 20 pieces of ATG1613*2.0-SU diamond composite chips after decobaltization and place them in a high-temperature resistant crucible, and place them in a vacuum heat treatment furnace. Embed the diamond layer in metal titanium powder. Use metal titanium The purity of the powder is ≥99.99%, the particle size is 1000 mesh, and the thickness of the titanium powder covering layer is about 1-2mm.
[0078] Step 2, first evacuate until the pressure in the furnace reaches 5×10 -3 Below Pa, start heating and continue vacuuming, raise the temperature in the furnace to 130°C and keep it for 0.5 hours, then continue heating for 2 hours, finally...

[0083] In this example, the same diamond composite sheet sample as in Example 1.1 is used as a product produced by Antai Iron and Steel Research Institute.
[0084] Specifically, in the strengthening treatment method, the final heat preservation temperature is kept at 735°C, and the rest of the process methods are exactly the same. After ATG1613×2.0-SU is carburized and strengthened at 735°C, the average value of the test impact toughness is 360J, and the heat resistance temperature is ≥ 785°C, and the wear ratio is about 350,000.
[0085] Before the strengthening treatment, the average impact toughness of ATG1613×2.0-SU test of the cobalt-removed composite sheet was 305J, the heat-resistant temperature was 750°C, and the wear ratio was 300,000.
[0086] Compared with the cobalt-removed composite sheet ATG1613×2.0-SU before strengthening treatment, its impact toughness value has increased by 18%, the heat-resistant temperature has increased by 35°C, and the wear ratio has incr...

[0088] The diamond composite sheet sample is purchased from a domestic manufacturer, the brand is PDC1613-ZGA (for oil drilling), the cobalt removal depth of the diamond layer is 1mm, and the quantity is 10 pieces.
[0089] The specific reinforcement processing methods are as follows:
[0090] Step 1. Clean 10 pieces of PDC1613-ZGA decobaltized diamond composite sheets and place them in a high-temperature-resistant crucible, and place them in a vacuum heat treatment furnace. Embed the diamond layer in metal titanium powder. It is ≥99.99%, the particle size is 1000 mesh, and the thickness of the titanium powder covering layer is about 1-2mm.
[0091] Step 2, first evacuate until the pressure in the furnace reaches 5×10- 3 Below Pa, start heating and continue vacuuming, raise the temperature in the furnace to 140°C and keep it for 0.5 hours, then continue heating for 2 hours, finally keep the temperature in the furnace at 730°C, and the pressure in the furnace is stable at 8×10...
