[0028] The preparation method of an oxide-reinforced multi-layer high manganese steel wear-resistant hammer head provided by the invention, the specific operation steps are as follows:
[0029] Step 1, using the traditional sand casting method to prepare the hammer handle, followed by sand mold making, metal smelting, pouring, cleaning, and machining the surface of the mounting hole on the hammer handle for fine polishing, grinding and scraping;
[0030] Step 2: Weigh the following materials by mass percentage: iron powder 10-20%, the rest is one or more of alumina powder, titanium oxide powder, zirconia powder, the sum of the mass percentages of the above components is 100% ;
[0031] Step 3: Use a planetary high-energy ball mill to mill and mix the materials weighed in step 2. The speed of the ball mill is 300-400r / min, the ball-to-material ratio is 10:1-30:1, and the ball-milling time is 6-24 hours. Drying, and then grinding to make fine powder after drying, the fine powde...

[0042] Step 1, using the traditional sand casting method to prepare the hammer handle, followed by sand mold making, metal smelting, pouring, cleaning, and machining the surface of the mounting hole on the hammer handle for fine polishing, grinding and scraping;
[0043] Step 2: Weigh the following materials by mass percentage: iron powder 20%, the rest is titanium oxide powder, the sum of the mass percentages of the above components is 100%;
[0044] Step 3: Use a planetary high-energy ball mill for ball milling and mixing the materials weighed in step 2. The speed of the ball mill is 400r / min, the ball-to-material ratio is 30:1, and the ball milling time is 24h. After the mixing is completed, place it in a vacuum oven at 90°C Dry for 2 hours, and then grind to make fine powder after drying. The fine powder is the powder that is sieved with a 200-mesh sieve after grinding;
[0045] Step 4: Press the fine powder by ordinary molding or cold isostatic pressing, and the pressing ...

[0052] Step 1, using the traditional sand casting method to prepare the hammer handle, followed by sand mold making, metal smelting, pouring, cleaning, and machining the surface of the mounting hole on the hammer handle for fine polishing, grinding and scraping;
[0053] Step 2: Weigh the following materials by mass percentage: iron powder 10%, the rest is alumina powder, and the sum of the mass percentages of the above components is 100%;
[0054] Step 3: Use a planetary high-energy ball mill for ball milling and mixing the materials weighed in step 2. The speed of the ball mill is 300r / min, the ball-to-material ratio is 10:1, and the ball milling time is 6h. After the mixing is completed, place it in a vacuum oven at 100°C Dry in medium for 2.5h, and then grind to make fine powder after drying, the fine powder is the powder sieved with 200 mesh sieve after grinding;
[0055] Step 4: Press the fine powder by ordinary molding or cold isostatic pressing, and the pressing pressu...
