New description: [New technical field] This creation is related to the structural improvement of a golf club head, especially one with large size, large striking area, large sweet spot range, high rebound coefficient and high The energy conversion coefficient, high hardness, good wear resistance, large frictional resistance of the impact surface, can reduce the side rotation and back rotation of the ball, and have better durability and practicality of the golf club head. • [Prior Art] Current golf clubs are usually divided into woods, irons, irons and pushers. Wood (wood) is also known as "metal woods", and can be made from materials such as steel, titanium, and fiberglass. The most popular improvement on "metal woods" consists of a lightweight but strong titanium alloy. And the mainstream "metal wood poles" are made of titanium alloy. φ The “metal wood poles” currently used for opening rods are their size in terms of their volume. The GM's open-rod "metal wood" club heads are all larger than 300 cubic centimeters (cc), although the maximum size of the club heads specified in the US Golf Association regulations is 460 cubic centimeters. (cc), but the non-competition club head will even reach 600 cubic centimeters. Large-size, large-volume club heads have a large "sweet spot" and high inertia, so they also have a large tolerance for hitting the ball. A large-size, large-volume club head is usually designed to make the crown and the bottom of the 5 M285376 thinner, making the roots and toes thicker. And moderately adjust the center of gravity of the shot, then hit the ball, even if you do not hit the center of the face, it will not make the ball twist, reduce the rotation of the ball, and increase the rebound coefficient, so that the ball flight distance is longer. The current club head made of titanium alloy has many shortcomings. For example, titanium metal materials are expensive, must be melted, cast and welded in a vacuum, and have high equipment and high manufacturing costs. In order to manufacture a large-sized club head, the wall thickness of the hollow club head must be reduced, resulting in uneven thickness of the finished product, and many product defects. The subsequent repairing and processing procedures are complicated, and it takes a lot of manpower, material resources and time. The club head, which is generally made of an aluminum alloy material, has a density of about 2.7 gram/cm 3 and a titanium alloy density of about 4.5 gram per centimeter, thereby knowing that the density of the aluminum alloy is only six percent of the density of the titanium alloy. ten. In order to control the flexibility of the shot, the weight of the club head must be controlled within a certain range. The heavier club head has a larger inertia and the shot is farther away. Due to the low density of the aluminum alloy, the club head can have a larger volume under the same weight; therefore, the club head made of aluminum alloy material can increase its size and volume to increase the sweetness of the striking surface. The club head made of aluminum alloy material can be used for forging, gravity casting, vacuum die casting, atmospheric pressure casting, etc., and has a relatively low cost advantage. In order to strengthen the hardness of the aluminum alloy material club head, T6 is usually applied. The precipitation hardening treatment, or the surface hard anode treatment is applied to increase the overall strength and strengthen the hardness of the impact surface, so as to reduce the energy loss when hitting the ball due to excessive deformation of the impact surface. However, the aluminum alloy striking surface which is hardened by hardening and hard anodizing still has insufficient hardness, insufficient thickness of the hardness layer, poor durability of the club head, and poor feeling of hitting the ball. Although it has the advantage of low system, it has not been able to match the mainstream titanium alloy club head M285376, and still plays a supporting role in the market. [New content] Therefore, the main purpose of this creation is to make the golf club head have the advantages of large size, large striking area, large sweet spot range, etc., and the golf club head has a high rebound coefficient and high The energy conversion coefficient, the hardness of the hard layer is high, the wear resistance is good, the frictional resistance of the striking surface is large, the side rotation and the back rotation of the ball can be reduced, and the durability and practicability are better, and the creation can make the ball hit. 10 flying farther 'the flight is more stable. For the above purposes, the present invention is a structural improvement of a golf club head having a club sleeve for combining a club and a hitting surface for hitting the ball, wherein the club The base material is composed of a base material and a hard layer coated with the base material _ which has a high external hardness, and the base material is made of an aluminum alloy, and the hard layer is nickel and hard ceramic particles, or nickel, phosphorus and A composite material composed of hard ceramic particles, and the face has a thick hard layer. • [Embodiment] Please refer to “1st, 2nd, and 3rd drawings” for the three-dimensional external view, front view, and A-A profile status of this creation. As shown in the figure: The present invention is a structural improvement of a golf club head having a club 1 and a club head 2, which is composed of a rod cover 2 1 and a crown portion 2 . The toe portion 2 3 , the bottom portion 24 , the hollow portion 25 , and the striking surface 26 are formed by a base material and a hard layer 27 coated on the outside of the base material. The base material is made of alloy, and the hard layer 27 is a combination of two or more ceramic particles or composites of 'phosphorus and hard ceramic particles. 6 6 has a thick hard layer. 1. The base material of the 8th "Hui Cup Head 2" is a high-strength aluminum alloy, especially for those who can implement #析, hardening, and the alloy base material of the head 2 can be forged, sophomore prayer , by gravity casting, etc., the base material after precipitation hardening is suitable for the appearance of the shape. For example, car, milling, grinding, etc. can be used for the plating operation. Typical aluminum alloy plating operations, including skim, micro Eclipse, pickling, word replacement, electroplating, etc. The manufacturing process is the same. The hard layer 2, 2 6 1 is mainly composed of nickel-hard ceramic particles, or recorded-phosphorus hard ceramic particles, by appropriate The electro-mineral conditions allow the recording, phosphorous and hard ceramsite to be simultaneously deposited on the surface of the |3 alloy base material, and form a hard layer of hard and hard layers 2, 261; the hard layer 2, the soft part of 261 is Ni The hard part is _, and the hard f Tao granules. The hard enamel ceramic particles of the Eighth Province mainly refer to the hardness value greater than 15 〇〇': the average particle size is less than i 〇 _ of the ceramic particles, such as · · carbon Fossil eve, nitriding, carbonized crane, oxidized! g, occupational titanium, material, formed hard layer hard The value is about Ην5 0 〇~Hv8 〇〇, the best value is _ 〇〇~, 7 5 0, and after processing, the surface hardness value is about Ην5 〇〇~My】〇00, the best value is Hv70〇 ~Hv9〇〇. The thickness of the hard layer 27, 261 can be changed according to the actual application conditions. The hard layer 269 on the striking surface 26 is thicker than the striking surface, and the mass layer 27 can be thinner. The energy of the hitting ball is higher than the coefficient of change, and a higher coefficient of restitution is obtained, which increases the hardness and thickness of the surface of the M285376, and the thickness of the coating of the striking surface is 3 Q //m~5 Ο Ο The most & value is 50" m~2 5 0 //m' The thickness of the non-face is from 10//m~lOQvm, the best value is go" m~3 〇β m , hard layer at different positions 2 7, 2 6 1 thickness can be changed by changing the shape of the anode, or by masking, covering, affixing, etc. If so, the structure of the above-mentioned structure constitutes a new structural improvement of the golf club head. Refer to Figure 4, which is an example of the hard layer of the creation of the face. See Figure 5 for more details. 2 6 rebound coefficient, • You can also first make the groove of the Lu alloy to make the groove 2 6 2, and then apply electroplating to increase the golf ball flight trajectory when increasing the shot, usually increase the impact surface 2 6 Area, increase the size and volume of the club head 2, adjust the weight to properly prevent the back spin. - Since the weight of the golf club head 2 is limited in design, it is generally between 2 gram and 300 gram. In order to increase the area of the sweet spot and stabilize the flight after the golf ball is hit, the "metal wood" is made into a hollow form. • Since the aluminum alloy is lighter than the mainstream titanium alloy, it is made into a hollow form. 'More can increase the size and volume of the ball head. The thickness of the striking surface of the striking surface can ensure the hardness of the ball when it hits the ball. τ, the excess weight can be distributed to the toe 2 3 and the root 2 to increase the sweetness. The area of the point increases the stability of the ball's flight path after hitting the ball. Please refer to Figure 6 for a schematic diagram of the plating status of this creation. As shown in FIG. 7F, the rod head 2 is connected to the cathode lead 31 of the power supply 3, a soluble nickel anode 3 2 (nickel ball or nickel sheet, nickel plate and nickel strip) and the power supply 3 The anode lead 33 is connected, and in the plating tank 34, the M285376 is recorded with a base acid or a nickel sulfate as a main key liquid 3, and the hard liquid ceramic particles are added to the plating liquid 35, and the plating liquid composition is appropriately adjusted. And the plating time, current and other conditions, finally obtain the hard layer phosphorus content 〇. 5 wt% ~ 1 〇 wt%, the optimum value is 0 · 6 wt% ~ 3 wt%; the hard ceramic particles content is 1 wt% ~ 10 0%%, the best value is 2 wt% ~ 4 wt%, and the plating conditions can be adjusted appropriately to increase the surface roughness of the hard layer 2 6 1 , increase the frictional resistance, and prevent the side rotation when hitting the ball. Back spin phenomenon. Please refer to "Figure 7" for a schematic diagram of the state of use of this creation. As shown in the figure _: When the user uses the present club head 2 to hit the golf ball 4, the striking surface 26 will be slightly concave, but since the surface hardness of the striking surface 26 is high, the rebound coefficient is high and the rebound force is increased. In addition, the rebound force generated by the face of the face is reduced, so that the golf ball 4 travels farther; and because of the large frictional resistance of the surface, the golf ball 4 is knocked out and the side spin and back spin phenomenon are reduced. Make the ball's flight obstruction more stable. Table T, above, the structural improvement of the creation of the golf club head can make the high-volume club head have the advantages of large size, large striking area, large sweet spot range, and the like, and the golf club The head has a high rebound coefficient and a high energy conversion coefficient. The hardness of the hard layer is high, the wear resistance is good, the frictional resistance of the impact surface is large, the side rotation and the back rotation of the ball can be reduced, and the durability and practicability are better. The creation can make the hitting ball fly farther and the flight path is more stable, which makes the creation of this creation more progressive, more practical, and more in line with the requirements of the system. It has indeed met the requirements of the new patent application. patent application. However, the above is only the preferred embodiment of the present invention. When it is not possible to limit the scope of this creation, the simple equivalent of the patent scope M285376 and the content of the creation manual is required.
