Iron golf club head with hardened layer

Abstract

The invention relates to an iron golf club head with a hardened layer. The iron golf club head is provided with a ball-striking panel part, a cutter part, a bottom part, a back part, a tube stem part and a neck part, wherein the outer surface of the iron golf club head is provided with the hardened layer, the hardened layer is distributed on the ball-striking panel part, the cutter part and the bottom part, the thickness of the hardened layer is within 1.5mm, the hardness of the hardened layer is HV250-450, and the hardness of the parts, without the hardened layer, of the iron golf club head is HV150-250.

Description

technical field [0001] The present invention relates to a golf iron club head with a hardened layer, in particular to a golf iron club head with a hardened layer only on a part of the surface. Background technique [0002] Press, carburizing or nitriding treatment on the golf iron club head can form a club head face hardening layer, and the club head face hardening layer can increase the hardness of the club head face and increase the flying distance of the golf ball hit. The so-called carburizing treatment is to put the workpiece into the carburizing medium, heat and hold the temperature for a period of time, so that the activated carbon atoms decomposed from the carburizing medium can penetrate into the surface of the workpiece, so that the carbon content of the surface of the workpiece can be increased and the hardness can be improved. The interior of the workpiece retains plasticity and toughness because the original composition is still maintained. With the help of carb...

Problems solved by technology

[0005] Although the above-mentioned previous documents disclose that carburizing the surface of the ball striking faceplate or the golf iron head can improve the hardness and wear resistance of the ball striking faceplate or the overall golf iron head, however, the golf iron head in actual use , not only the hardness of the hitting panel will affect the user's hitting feeling, but also the hardness of the back, blade, bottom and neck of the golf iron head is also closely related to the performance of the golf iron head, for example: when When the hardness of the blade portion is low, more materials must be used to make the blade portion have good wear resistance, which will limit the position of the center of gravity of the golf iron head and make the playing feel simplistic. Therefore, if only The hardness of the hitting panel has been increased, which may not be able to meet the different needs of different users.
