Experimental investigation on wire-spraying feeding powder composite surfacing used in subsoiler

With the purpose of solving the problem that traditional subsoiler was easy to wear, the new process of wire-spraying feeding powder composite surfacing was proposed which surfacing coatings on the easily-worn subsoiler parts was sprayed. The microhardness and the abrasive wear resistance and microscopic wear morphology of surfacing subsoiler were tested. The results show that the appearance of weld was good and a good metallurgical bonding state was found between welding layer and substrate. Microhardness reach up to 831HV0.2. The wear resistance has been increased by 2-3 times compared with traditional subsoiler, thus extending the service life of the subsoiler farming.
