Embodiment 1
[0016] Embodiment 1, an ultra-high hardness wear-resistant film, the film is made of the following raw materials according to mass percentage: metal organic salt 5-10%, inorganic salt 60-90%, auxiliary agent 0.1-5%, surfactant 0.5-3%, the sum of the mass percentages of each raw material is 100%. The metal organic salt is in the form of oleate or oleylamine salt of iron or titanium or cobalt or nickel or copper or chromium. The inorganic salt is sodium chloride and / or potassium chloride. The auxiliary agent is urea and / or melamine. The surfactant is cetyltrimethylammonium bromide or cetyltrimethylammonium chloride.
Embodiment 2
[0017] Embodiment 2, a kind of production method of ultra-high hardness wear-resistant film, the preparation steps of this production method are as follows:
[0018] (1) According to the raw material ratio described in claim 1, weigh the metal organic salt into the container and add water to dissolve it. According to its valence state, add sodium oleate or oleylamine, stir evenly, and put it under the condition of 60-90°C , aged in an open system for 24 hours, dried for later use;
[0019] (2) Then, add inorganic salts, auxiliary agents and surfactants to the above raw materials and grind them evenly for later use;
[0020] (3) Put the above-mentioned raw materials in a tubular muffle furnace, protected by an argon atmosphere, condition: 0.04SLPM, place the metal or ceramic substrate at a distance of 1-5cm from the above-mentioned raw materials, and heat up at a rate of 5-10°C / min Heat to 600-800°C, reduce the gas speed to 0.01SLPM, and keep warm for 2-4 hours;
[0021] (4) ...
Embodiment 3
[0022] Embodiment 3, a production method of an ultra-high hardness wear-resistant film, comprising the following steps: (1) Weigh 27 grams of ferric chloride hexahydrate and 6 grams of water, add them to a beaker, and add 91.2 grams of oil Sodium acid, stir evenly, age in an oven at 60-90°C for 24 hours, and dry to obtain the precursor;
[0023] (2) Add 1180 grams of sodium chloride or potassium chloride, or a mixture of the two in any proportion, to the above raw materials, add 3.6 grams of cetyltrimethylammonium bromide and 6.0 grams of urea, and grind them evenly;
[0024] (3) Put the above-mentioned raw materials in a tubular muffle furnace, protect with argon atmosphere (0.04SLPM), place the metal / ceramic substrate at a distance of 1-5cm from the above-mentioned raw materials, and heat at a heating rate of 5-10°C / min To 600-800 ℃, reduce the gas speed to 0.01SLPM, keep warm for 2-4 hours;
[0025] (4) Cool to room temperature to get the product.
