The Strange History of Galvanizing Metal

 

In the 1700s, the effects of electric current were just beginning to be studied by scientists, but weren’t yet connected to metallurgy. Here is a general history of the galvanizing process, its earliest uses, and how it got the unusual name.

 

Galvani and Volta

 

Luigi Galvani was the first scientist to discover that electric current can pass through a cadaver, and he experimented with using two different metals to conduct the current. Alessandro Volta, whose name gives us the “volt”, read Galvani’s work and expanded on the concept of using metals to conduct electricity. He went on to invent the first modern battery. In only a few years, the concepts became so popularized due to the two men’s work that the term “galvanizing” came into use, although in reference to imbuing people with a motivating force, not industrial practices.

 

Further Discoveries and Patents

 

A man named Sir Humphrey Davy in the 1820s created an experiment that applied an electric current to two metals in submerged in water. This experiment showed that one metal corroded and the other was protected – forming the first evidence that one metal could be “sacrificed” to coat another. In the mid 1830s, a Frenchman named Sorel was actually the first person to invent the modern method of galvanizing – dipping iron into plating tanks of molten zinc using electrical current – and patented his process with the name “galvanizing”.

 

Early and Modern Uses

 

By the 1850s Britain was using thousands of tons of zinc per year to coat iron and steel for construction and naval purposes. The methods were subsequently refined, and now there is a worldwide industry of galvanization because of its varied uses in everything from cars to lawn furniture.

This technique that began with cadavers has changed our world completely. Thousands of industries and products wouldn’t exist or would be completely different without galvanization. Whether you’re a student, part of industry, or just curious, take some time to research this fascinating process. You won’t regret it.…

Super Tips From The Experts About Web Hosting

When you first decide to create a website you’re focused on many things, such as buying a domain name or the site’s design, and hosting tends to fall by the wayside. Once your site is built you’re suddenly in a scramble to get it online, but where do you start? This article will help you by providing information which will allow you to find a perfect web host.

Switch web hosts if an outage lasts for more than a day. Even if the host explains why the server is down, the most likely reason is that the host did not invest enough into back up plans as far as outages are concerned. Any truly professional web hosts will have ensured that outages will be short and infrequent.

When choosing a web hosting service, refrain from going with the recommendation of friends or family who are not professionals. Though they may have had a good experience themselves with a certain provider, realize that their needs may be very simple compared to yours. Read reviews and advice from those who have needs similar to your own.

Keep track of how many often outages occur and how long they last. If they are too long and too frequent, you should think about choosing a different service. Most services encounter issues once in a while but if they are not fixed quickly, you are not getting your money’s worth.

Avoid free web hosting services. These services support themselves by placing advertisements on the top of all the websites they host. These advertisements may annoy your visitors or make your site appear unprofessional. In addition, some free hosts may restrict the amount of commercial content allowed on the websites that they host.

If at all possible, choose a web host that has 24-hour customer service via telephone. The larger hosting services often provide this valuable service. You do not want to be working late at night and find that are experiencing technical difficulties. Call them before you sign up, and test the level of expertise of the agents, and whether or not they can give simple instructions that are easy to understand.

Find out if your web host service supports videos. Videos take a lot of storing space and bandwidth, and you might have to spend a lot for a plan that supports videos. You can save money by uploading your videos to YouTube for free and embedding them on your website.

Don’t choose your web hosting provider based solely on price. Although using a cheap or free web host may save you money in the short run, these hosts might not offer the disk space or bandwidth you need. Price should be only one factor in your final decision so that you ensure that you get what you most need.

Ensure that you figure out a solid budget and use it to find the plan which works best for you, then move forward and select a web host. Once you put the tips in this article into practice you’ll be able to find a great web host quickly and easily.…
