Where have we been?

Are you getting this publication as a surprise? Well hopefully not, but we (I) have been very lax in my efforts to keep up with the publication since its inception a couple of years ago..  Busy, busy, busy.  But Mr. Postle insisted that our readers need to hear from us on a regular basis.  So I have made it my business to keep up. I promise, you will hear from us on a regular basis.

"Clues For Evaluating Wear Mechanisms "

It has been said that 80% of all wear is abrasive in nature. From my experience it appears to be pretty accurate. This would lead to a rather simple solution to solving wear problems, since the cause is usually abrasive. Wish it were that easy. But then again, some of us wouldn't have jobs if it were that easy. Allow me to take some liberties here and re-quote that statement. "80% of all wear is PREDOMINATELY abrasive in nature". Notice the catchword "PREDOMINATELY". It has been my experience that most wear is a combination of wear mechanisms which may include one or more of the following: * Corrosion * Erosion * Metal to Metal or Adhesive Wear * Impact * Galling * Thermal Fatigue * Abrasive Wear.  It is the "Other" wear mechanisms in combination with abrasive wear that cause all the problems. It is only until the other mechanisms are recognized that a successful solution to the wear problem can be achieved. The identification process can be very difficult because of the subtle nature of the "Other" mechanisms. Impact, for example is often undetected or underrated. Think for a moment about water dripping from a rock crevice onto a rock ledge. Doesn't appear that would create any impact at all, but it is the major wear factor from the rock ledges viewpoint. Huge gullies are formed in this manner. Some forms of Erosion for example, can be caused by minute gas bubbles bursting and causing impact on a metal surface. This can result in extensive damage. Actually the list of "Other" wear mechanisms goes on. The point here is that, when evaluating a wear problem, look for the not so obvious. Look for the subtle mechanisms that might be at work. Don't be too hasty to make a judgment. If a wear problem has been persistent despite numerous attempts to solve it, its solution usually lies in the subtle wear mechanism that no one else has been able to detect.

*****************************************************************************************************************

An American businessman was at a pier in a Mexican village when a small boat with just one fisherman docked. Inside the small boat were several large tuna. The American complimented the man on the quality of his fish and asked how long it took to catch them.

The man replied, “Only a little while.”

“Why don’t you stay out longer and catch more fish?” asked the American.

The Mexican shrugged. “I have enough for my family’s needs.”

“But what do you do with the rest of your time?” asked the American.

“Well,” replied the Mexican, “I sleep late, fish a little, play with my children, take siesta with my wife Maria, and stroll into the village each evening where I sip wine and play guitar with my amigos. I have a full and busy life, señor.”

The American scoffed, “I am a Harvard MBA and could help you. You should spend more time fishing and, with the proceeds, buy a bigger boat. With the proceeds from the bigger boat, you could buy several boats. Eventually you would have a fleet of fishing boats. Instead of selling your catch to a middleman you would sell directly to the processor, eventually opening your own cannery. You would control the product, processing, and distribution. You would need to leave this small coastal fishing village and move to Mexico City, then LA, and eventually New York where you will run your expanding enterprise.”

The astonished Mexican fisherman asked, “Señor, how long will this all take?”

“15-20 years,” answered the American.

“But what then, Señor?”

The American laughed: “That’s the best part! When the time is right, you will announce an IPO and sell your company stock to the public and become very rich. You would make millions.”

“Millions, Señor? Then what?” asked the incredulous Mexican.

“Then,” beamed the American, “You would retire. Move to a small coastal fishing village where you would sleep late, fish a little, play with your kids, take siesta with your wife, and stroll to the village in the evenings where you could sip wine and play your guitar with your amigos.”
