Problem: Joining of Advanced Materials Improves Sports Equipment
Titanium, beryllium, tungsten, nickel alloys, composites, advanced
ceramics and even diamonds are emerging as possible materials
for various sports equipment, in particular golf club components.
These materials, due to their unique properties such as weight,
strength to weight ratios, stiffness, toughness, hardness,
and modulus, have the potential to increase the performance of
various clubs. In particular, low club weights, localized weighting,
high stiffness and high modulus are increasing the use of titanium
and opening the possibility for the use of beryllium alloys. These
alloys plus the need for assembly and wear resistant ball striking
surfaces, make the joining of a combination of materials essential.
Many times mechanical or epoxy bonding limits design flexibility,
appearance and lowers reliability due to poor epoxy strengths.
Thus, metallic joining compounds are needed that can wet and bond
a variety of very difficult to join materials. Simultaneously,
the joining process must be economical while producing high reliability
MRis S-Bond® is a versatile, ductile bonding process
which bond any of the materials an/or any materials combinations,
now being considered for golf clubs.
· Stainless steel to titanium/beryllium
· Tungsten to titanium
· Carbides to steel and/or titanium
· Diamonds composites
Its characteristics make S-Bond® suitable for economic processing
since the joining can be done in air and without the use of flux.
Low temperature processing reduces discoloration and distortion.
This minimizes post braze working and clean up operations, which
are typically time consuming manual operations. Short heating
cycle times, especially using MRis induction heating systems,
make S-Bond® joining fast. Long furnace brazing or curing
times can be eliminated. Additionally, without lead and without
the use of chemical fluxes, S-Bond® is an environmentally
friendly manufacturing method. It is a metallic joining compound,
hence, the performance of the joining is superior to epoxy and
mechanical fastened joints. The ultraviolet from the sun, heat
damage and stresses from rough handling and cold club storage
can degrade epoxies. These circumstances wont degrade S-Bond®
since it is a metallic alloy. Alternatively, mechanical joints
can loosen and fracture with use. The metallic S-Bond® braze
joint assures the toughness needed to withstand the high striking
forces imposed on clubs.
Problem: Inserts for Wear Protection for Surfaces
(Moving Parts and Cutting Surfaces)
Many times moving components in abrasive or erosive environments
need to be protected. Examples include slideways, mixers, dies,
mandrels, molds, knife blades, conveyor components, etc
materials that are typically used to protect these metal components
are either carbides (e.g. cemented tungsten carbides) or ceramics
(e.g. alumina, silicon nitride, even diamond), These materials
are typically molded then brazed to the metal surfaces. The current
metal/ceramic joining techniques are multi-step, expose the base
component to high temperature and require vacuum. Thus, the processes
to apply such wear surfaces can be too expensive and/or cannot
be easily used in the field. Brazing inserts into blade edges
normally exposes the rest of the cutting tools and blades to high
temperatures. This can distort the tool and thus create considerable
rework or in the worst case render the tool unusable. Additionally,
the current vacuum braze processes are expensive and not easy
to do in house.
Solution: S-Bond® Joining
The S-Bond® joining processes is a low temperature joining
material, which can be heated in air and by design is active and
thus readily bond ceramics to metals. These characteristics greatly
simplify the joining process for metals to ceramics. This flexibility
lowers the processing costs and enables most shops to join previously
difficult to join materials. The lower processing temperatures
reduce tool discoloration and distortion, thus reducing post joining
operations. Provided the cutting interfaces will not exceed 4000C
(7500F), S-Bond® can be a solution for many cutting
tool and wear surface applications.
