Starting an engine can be relatively easy nowadays. You can get your car roaring just by simply Inserting and turning the key or even remotely through a phone. While things were a lot different 100 years ago, you might have to be strong enough to drive ‘cause the hand cranks were really exhausting. Then multiple types of starters were invented. After continuous upgrading, the electric starters that we recognize today are widely used in various kinds of engine startup. As for those old types, mostly disappeared in the long history. But the interesting thing is, one of them remains in service for all these time, and is gradually becoming an irreplaceable spring starter.
The history of engine starters
As mentioned above that hand-crank starter was what we use for startup 100 years ago. It is the original starter motor of all, widely used in the 1900s. The hand cranks gave our motorized vehicle its very first initial driving force, but honestly, they were lagging. The biggest problem with the hand-cranked starter is its unguaranteed safety. You turn the cranks, the cranks can turn against you and gives you a bone-breaking kickback.
To improve simplicity and safety, spring-powered and gunpowder starters were created. A spring starter motor also need to be cranked, but you can bring the physical work forward. Its working principle is to convert and store kinetic energy in the spring to start engines after, removing the process which can cause a kickback. Similarly, the gunpowder motor uses the energy from the explosion to start the car. No manpower required.
The revolutionary “electric starting system” was patented in 1911. The Cadillac model of 1912 was the first to install this motor because it was the first car with a complete circuit, and that’s what we know as the start of modern engine-starting technology. After that, key-operated ignition and other enhancing techs were gradually added in, the engine start has become more diverse.
Why is spring starter still in service?
While it actually had retired for civilian cars, but returned in many other fields. The applications of mechanical spring starter extended to firefighting, emergency rescue, military, marine, Petroleum industry, etc. Mostly it’s used to initiate a diesel engine as an alternative starting system when there is no power source available. Yes, we came to realize that humans are walking batteries.
You might have noticed that a lot of diesel engines have more than one bore (or at least one detachable bore), leaving rooms for backup starters. In many situations we might suffer from property or even life loss because the battery of our diesel engine is dead. That’s why a backup starting system is necessary in emergency operations. Another factor is that many emergency operations are carried out in harsh environments like explosion-proof situation, meaning no electric allowed. So when you see someone turning a hand crank in a factory instead of a gym, don’t worry, you did not travel back to 1885.
Will spring starters be even longer-last than the electrics?
The way I think of it? Yes. The spring starter is one of the most primitive types of this tech, but it does not have the fatal drawbacks of a hand crank. Over the years, engines are constantly evolving and changing, but the spring starter’s simplicity and practicality made it through and kept it alive. Since it’s primitive enough, no magnetism, no circuit, no oil grease, it’s possible to start up a machine in almost any place and at any time. The only problem is a mechanical spring starter requires manpower, but manpower is exactly something we can take at any time. So I do think it’s probably the best alternative starting system and will stay that way for a very long time.

Tungsten carbide is an alloy material made of hard compounds which are consist of refractory metals and bonding metals, through powder metallurgy. Carbide parts have a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance and corrosion resistance, especially its high hardness and wear resistance, which remains basically unchanged even at a temperature of 500°C. It still has a high hardness at 1000°C.
The development history of tungsten carbide
In 1923, Schroeter who is from Germany added 10% to 20% of cobalt to tungsten carbide powder as a binder and invented a new alloy of tungsten carbide and cobalt. The hardness is second only to diamond, which is the first artificially made first cemented carbide in the world. When cutting steel with a tool made of this alloy, the cutting edge will wear out quickly, and even the cutting edge may crack. In 1929, Schwarzkov, from the United States, added a certain amount of compound carbide of tungsten carbide and titanium carbide to the original composition for improving the performance of the tool in cutting steel. This is another achievement in the development history of tungsten carbide.
In the past two decades, coated cemented carbide has also come out. In 1969, Sweden successfully developed a titanium carbide-coated tool. The matrix of the tool is tungsten-titanium-cobalt cemented carbide or tungsten-cobalt cemented carbide. The thickness of the surface titanium carbide coating is only a few microns, but compared with the alloy tools of the same brand, The service life is extended by 3 times, and the cutting speed is increased by 25% to 50%. The fourth generation of coated tools appeared in the 1970s, which can be used to cut difficult-to-process materials.
Wide applications of tungsten carbide
Tungsten carbide is widely used as tool materials, such as turning tools, milling cutters, planers, drills, boring cutters, etc., for cutting cast iron, non-ferrous metals, plastics, chemical fibers, graphite, glass, stone and ordinary steel, and can also be applied for cutting hard-to-process materials such as heat-resistant steel, stainless steel, high manganese steel, tool steel, etc. It is used to manufacturing cutting tools, cobalt tools and wear-resistant parts, and is widely applicable in the military industry, aerospace, mechanical processing, metallurgy, petroleum drilling, mining tools, electronic communications, and other much more fields.
Carbide products have high hardness, high strength, excellent wear resistance and corrosion resistance and have been widely used in various industries. The excellent material properties of tungsten carbide make it become more and more important tool materials.
